FUNCTIONAL DESCRIPTION

The TEA1501 contains a high voltage power switch, a high
voltage startup circuit and low voltage control circuitry on
the same IC. Together with a transformer and a few
external components a low power, isolated, flyback
converter can be built. The Greeny system operates in a
burst mode. During each burst period the output voltage is
regulated to a desired voltage level.

System operation

O

N/OFF

The Greeny system can be switched on and off by means
of a low cost, low voltage switch. In the Off mode the
startup current source and power switch are disabled. In
the On mode, Greeny delivers the startup current for the
supply capacitor and after the supply voltage reaches the
startup level Greeny activates the power switch.

S

TARTUP

The startup is realized with a high voltage startup current
source instead of a dissipative bleeder resistor which is
commonly used by low voltage control ICs. When Greeny
is switched on, the startup current source is enabled and
starts charging the Vaux capacitor. The startup current
level is high and accurate (typical 1.8 mA) which results in
a well-defined and short startup time, within 0.25 s. After
the supply voltage reaches the startup level the current
source is switched off and the Vaux capacitor supplies the
chip. Reducing the power dissipation in the current source
to zero after startup is one of the green features of Greeny.

O

PERATION

After startup the flyback converter starts delivering energy
to the secondary and auxiliary winding. The Greeny
system works with fixed switching frequency and fixed
peak current.

As all the windings of the flyback transformer have the
same flux variation, the secondary voltage and the
auxiliary voltage are related via the turns-ratio (n

s/na

).
Therefore, the isolated secondary voltage is controlled by
the non-isolated auxiliary voltage.

The burst mode operates by switching at high frequency
until the Vaux voltage reaches its regulation level of 20 V.
Greeny stops switching until the time period set by the
burst oscillator has expired. At the start of the next burst
period Greeny starts switching at high frequency and
repeats the cycle again.

To guarantee a stable operation in a burst mode controlled
system a Vaux slope compensation circuit is integrated in
Greeny. The Greeny system delivers a constant voltage to
the secondary load until a burst duty cycle of 40%.

D

ATA TRANSFER

The TEA1501 has a data transfer function which makes
communication from the isolated secondary side to the
non-isolated primary side of the transformer possible,
without using an opto-coupler. This communication
function is activated by increasing the secondary load.
With this data transfer function a main power supply can
be switched on and off by the Greeny system.

The power delivered to the secondary and auxiliary
winding is proportional to the number of primary current
pulses per burst period, provided that the converter
operates in discontinuous conduction mode. During each
burst period the number of primary current pulses is
counted. A threshold (N

data

) of 56 pulses is integrated. The
clamp level on the OOD pin is set to data-on level from
data-off level in case the N

data

threshold is passed. This
data-on clamp level can be sensed by the on/off input of a
main supply control IC of the GreenChip family. The
data-on clamp level is maintained until a burst appears
with a number of pulses below the N

data

threshold.

CIRCUIT BLOCK DESCRIPTION
On/Off/Data section

The On/Off/Data block contains a comparator for the on/off
level and is active if the drain voltage is above 50 V (DC).
The typical current consumption in Off mode is 40 µA. The
data signal changes the clamp level on the OOD pin to
indicate data transfer: low clamp level for data-off and high
clamp level for data-on.

Vaux management

The Vaux management block is active when Greeny is in
the On mode. This Vaux management block senses the
Vaux voltage and determines the state of Greeny: startup
or normal operation. During startup the following circuits
are active: On/Off/Data section, Reference block (partial),
Vaux management, Temperature protection and the
Startup current source.

Startup current source

The startup sequence is carried out using an accurate
startup current source. The startup current flows from the
Drn pin to the Vaux pin via the startup current source and
charges the Vaux capacitor. When Vaux reaches the
startup threshold the startup current is switched off and the
flyback converter starts operating and the output voltage
rises. The Vaux capacitor must be capable of supplying
the entire supply current (I

Vaux(LOW)

) until the output
voltage is in regulation. From that moment the Vaux
capacitor is charged by the flyback converter via the
auxiliary winding.

Reference block

The reference block contains a bandgap circuit which
determines all the accurate and temperature independent
reference voltages and currents. It defines the voltage
detection level for the primary current comparator and it
defines the voltage at the Ref pin. The value of the
reference resistor determines the burst frequency, the
switching frequency and the leading edge blanking time.

Temperature protection

The temperature protection circuit senses the chip
temperature using a proportional to absolute temperature
voltage (V

ptat

) generated in the reference block. If the chip
temperature exceeds 140 °C the power switch and the
startup current source are disabled. When the chip cools
down below 100 °C, the startup circuit is enabled again.

Switch oscillator

The switch oscillator determines the switching frequency
and the maximum on-time of the power switch. The
maximum on-time is set at 66% of the switching period.
The switching frequency is determined by the reference
resistor at the Ref pin and an internal capacitor. The
switching frequency can be adjusted in a range from
20 to 50 kHz, thus above the audible spectrum.

1998 Aug 19 8

Philips Semiconductors Preliminary specification

Greeny; GreenChip TEA1501

Burst oscillator

The burst oscillator generates a triangular wave signal for
determination of the burst frequency. The burst frequency
is determined accurately and temperature independent by
the externally connected reference resistor R

Ref

and burst

capacitor CBt.

Gate driver

The gate driver switches the power switch. The power
switch is turned on at the beginning of every oscillator
cycle and is turned off by the primary current comparator
or by the maximum on-time. The power switch is also
prevented from turning on if the Vaux voltage has reached
its regulation level or in case of active over temperature
protection or in case of active under voltage lockout
protection.

Power switch

The power switch is an integrated high voltage LDMOST
with a R

dson

of 40 Ω, a maximum peak drain voltage of
650 V, a maximum continuous drain voltage of 500 V and
a maximum drain current of 0.25 A.

Primary current comparator

The primary current comparator senses the voltage across
the external sense resistor R

Src

which reflects the primary
current. The detection level of the comparator is 0.5 V. The
power switch is switched off quickly when the source
voltage exceeds this detection level. The comparator has
a typical propagation delay of 80 ns. If the dV/dt of the
drain voltage has to be limited for EMI reasons, a capacitor
can be connected between the Drn and Src pins of
Greeny. The discharge current of this EMI capacitor does
not flow through the sense resistor R

Src

and does not

activate the comparator.

Leading edge blanking

To prevent the power switch from switching off due to the
discharge current of the capacitance on the Drn pin a
Leading Edge Blanking (LEB) circuit has been
implemented. The leading edge blanking time is defined
as the maximum duration time needed to discharge the
capacitance at the drain of the power switch. The leading
edge blanking time is determined by the reference resistor
to obtain an accurate and temperature independent time.
The LEB time tracks with the period time of the switch
oscillator.

Modulator

The modulator determines the regulation level of the Vaux
voltage. For a burst duty cycle from 0 to 40% the Vaux
voltage is regulated to 20 V. For stable operation in burst
mode a decrease in regulation voltage is integrated for a
burst duty cycle above 40%. At 100% burst duty cycle the
regulation voltage is 17.5 V.

Counter

The power delivered to the load (auxiliary and secondary)
is a function of the number of energy pulses per burst,
according to the following formula:

Whereη is the efficiency, L

p

is the primary inductance, I

prim

is the primary peak current, f

burst

is the burst frequency and

N is the number of pulses in one burst period.
The counter counts the number of pulses in each burst

period and detects if the N

data

threshold is passed. The
counter state is used for the data transfer function and for
the supply current tracking.

Supply current tracking

For obtaining good load regulation, especially with low
cost transformers, a tracking circuit is included. The
tracking circuit makes the supply current of Greeny a
function of the secondary load. This makes the voltage
drop across the series resistance of the auxiliary winding
proportional to the voltage drop across the series
resistance of the secondary winding. Therefore, the
secondary output voltage tracks with the Vaux regulation
voltage.

The tracking starts at a counter state of 28. For a counter
state from 28 up to 112 (typical values) the supply current
of Greeny rises linearly with the counter state according to
the following formula (see Fig.7).

For counter states of 112 and higher the supply current
remains on its maximum value.

LOW POWER STANDBY APPLICATION

Greeny can operate as a stand alone low power supply or
as a standby power supply incorporated in a main SMPS.

Together with a GreenChip TEA1504 a power supply
with ultra low standby power can be built where Greeny
supplies the microprocessor with the power on/off
indicator and the GreenChip controls the main power
supply during normal operation.

Operation modes
The power supply with a Greeny TEA1501 and a

GreenChip TEA1504 can be in three different modes,
according to the state of switches S1 and S2 (see Fig.9).

Table 1 Operation modes of power supply

Power supply in Off mode
The power supply can be switched on and off by means of

the functional switch S1. This functional switch replaces
the generally used high voltage mains switch. The power
supply is in Off mode if the switch S1 is open.

If the switch S1 is closed the voltage applied on the OOD
pin of Greeny is above the on/off level (0.7 V) and Greeny
starts up, the power supply enters the Standby mode or
the Normal operation mode.

S1 S2 OPERATION MODE

Open Open or

Closed

Greeny is in Off mode,
GreenChip is in Off mode, Power
supply is in Off mode.

Closed Open Greeny is On mode,

GreenChip is in Off mode,
Power supply is in Standby mode.

Closed Closed Greeny is in On mode,

GreenChip is in On mode,
Power supply is in Normal
operation mode.

When the switch S1 is opened the voltages on the OOD
pin of Greeny and the OOB pin of the GreenChip are 0 V.
The power supply and the power on/off indicator (LED) are
switched off immediately and the power supply is in the
Off mode again.

Power supply in Standby mode

When switch S1 is closed Greeny is in the On mode and
supplies the microprocessor and the power on/off
indicator. The microprocessor controls the state of switch
S2. The power supply is in the Standby mode when switch
S2 is open.

The output power of Greeny is determined by the
microprocessor and is below the P

data

level when switch
S2 is open. The clamp level on the OOD pin of Greeny is
the data-off level with a typical value of 1.3 V which is
below the on/off level of the GreenChip which has a
typical value of 2.5 V. The GreenChip remains in Off
mode.

Power supply in Normal operation mode

The power supply changes its operation mode from
Standby to Normal operation by closing the switch S2. The
switch S2 is placed at the isolated secondary side of the
Greeny and controls, via the data transfer function of
Greeny, the operation mode of the power supply.

When the microprocessor closes switch S2 the output
power of Greeny is increased. The output power exceeds
the P

data

level and the clamp level on the OOD pin of
Greeny is set to data-on level with a value of 4 V. The
voltage on the OOB pin of the GreenChip is above its
on/off level of 2.5 V and the GreenChip starts up.

The power supply enters Normal operation mode, Greeny
supplies the microprocessor and the GreenChip supplies
the main load.

SOLDERING
Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“Data Handbook IC26; Integrated Circuit Packages”

(order code 9398 652 90011).

Soldering by dipping or by wave

The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T

stg max

). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
