Pin Descriptions

Vin: The positive input voltage power node to the mod-

ule, which is referenced to common GND.

Vout: The regulated positive power output with respect
to the GND node.

GND: This is the common ground connection for the
Vin and Vout power connections. It is also the 0 VDC
reference for the control inputs.

Inhibit: The Inhibit pin is an open-collector/drain negative
logic input that is referenced to GND. Applying a low­level ground signal to this input disables the module’s
output and turns off the output voltage. When the Inhibit
control is active, the input current drawn by the regula­tor is significantly reduced. If the Inhibit pin is left
open-circuit, the module will produce an output when­ever a valid input source is applied.

Vo Adjust: A 0.1 W 1 % resistor must be directly connected
between this pin and pin 7 (GND) to set the output voltage
to a value higher than 0.8 V. The temperature stability of
the resistor should be 100 ppm/°C (or better). The set
point range for the output voltage is from 0.8 V to 3.6 V.
The resistor value required for a given output voltage
may be calculated from the following formula. If left
open circuit, the output voltage will default to its lowest
value. For further information on output voltage adjust­ment consult the related application note.

Vo Sense: The sense input allows the regulation circuit to
compensate for voltage drop between the module and
the load. For optimal voltage accuracy Vo Sense should
be connected to Vout. It can also be left disconnected.

Track: This is an analog control input that enables the
output voltage to follow an external voltage. This pin
becomes active typically 20 ms after the input voltage
has been applied, and allows direct control of the output
voltage from 0 V up to the nominal set-point voltage.
Within this range the output will follow the voltage at
the Track pin on a volt-for-volt basis. When the control
voltage is raised above this range, the module regulates
at its set-point voltage. The feature allows the output
voltage to rise simultaneously with other modules pow­ered from the same input bus. If unused, this input should
be connected to V

. Note: Due to the under-voltage lockout

in

feature, the output of the module cannot follow its own input
voltage during power up. For more information, consult the
related application note.

Margin Down: When this input is asserted to GND, the
output voltage is decreased by 5% from the nominal. The
input requires an open-collector (open-drain) interface.
It is not TTL compatible. A lower percent change can
be accomodated with a series resistor. For further infor­mation, consult the related application note.

Margin Up: When this input is asserted to GND, the
output voltage is increased by 5%. The input requires an
open-collector (open-drain) interface. It is not TTL
compatible. The percent change can be reduced with a
series resistor. For further information, consult the
related application note.

PTH03030W & PTH05030W

Capacitor Recommendations for the PTH03030 &

PTH05030 Series of Power Modules

Input Capacitor

The recommended input capacitor(s) is determined by
the 1,500 µF
minimum ripple current rating.

Ripple current and <100 mΩ equivalent series resistance

(ESR) values are the major considerations, along with
temperature, when designing with different types of
capacitors. Unlike polymer tantalum, conventional tan­talum capacitors have a recommended minimum voltage

rating of 2 × (maximum DC voltage + AC ripple). This

is standard practice to ensure reliability.

For improved ripple reduction on the input bus, ceramic
capacitors may be used to complement electrolytic types
and achieve the minimum required capacitance.

Output Capacitors (Optional)

For applications with load transients (sudden changes in
load current), regulator response will benefit from an
external output capacitance. The recommended output
capacitance of 330 µF will allow the module to meet
its transient response specification (see product data sheet).
For most applications, a high quality computer-grade
aluminum electrolytic capacitor is most suitable. These
capacitors provide adequate decoupling over the frequency
range, 2 kHz to 150 kHz, and are suitable when ambient
temperatures are above 0 °C. For operation below 0 °C,
tantalum, ceramic or Os-Con type capacitors are recom­mended. When using one or more non-ceramic capacitors,
the calculated equivalent ESR should be no lower than

4 mΩ (7 mΩ using the manufacturer’s maximum ESR

for a single capacitor). A list of preferred low-ESR type
capacitors are identified in Table 1-1.

Ceramic Capacitors

Above 150 kHz the performance of aluminum electrolytic
capacitors becomes less effective. To further improve the
reflected input ripple current or the output transient
response, multilayer ceramic capacitors can also be added.
Ceramic capacitors have very low ESR and their resonant
frequency is higher than the bandwidth of the regulator.
When used on the output their combined ESR is not
critical as long as the total value of ceramic capacitance
does not exceed 300 µF. Also, to prevent the formation of
local resonances, do not place more than five identical ce­ramic capacitors in parallel with values of 10 µF or greater.

Tantalum Capacitors

Tantalum type capacitors can be used at both the input
and output, and are recommended for applications where
the ambient operating temperature can be less than 0 °C.
The AVX TPS, Sprague 593D/594/595 and Kemet T495/
T510 capacitor series are suggested over many other
tantalum types due to their higher rated surge, power

(1)

minimum capacitance and 900 mArms

dissipation, and ripple current capability. As a caution
many general purpose tantalum capacitors have consider­ably higher ESR, reduced power dissipation and lower
ripple current capability. These capacitors are also less
reliable when determining their power dissipation and
surge current capability. Tantalum capacitors that do
not have a stated ESR or surge current rating are not
recommended for power applications.

When specifying Os-Con and polymer tantalum capacitors
for the output, the minimum ESR limit will be encoun­tered well before the maximum capacitance value is
reached.

Capacitor Table

Table 1-1 identifies the characteristics of capacitors from a
number of vendors with acceptable ESR and ripple current
(rms) ratings. The recommended number of capacitors
required at both the input and output buses is identified
for each capacitor type.

This is not an extensive capacitor list. Capacitors from other
vendors are available with comparable specifications. Those
listed are for guidance. The RMS ripple current rating and
ESR (at 100kHz) are critical parameters necessary to insure
both optimum regulator performance and long capacitor life.

Designing for Very Fast Load Transients

The transient response of the DC/DC converter has been
characterized using a load transient with a di/dt of 1 A/µs.
The typical voltage deviation for this load transient is
given in the data sheet specification table using the
optional value of output capacitance. As the di/dt of a
transient is increased, the response of a converter’s regu­lation circuit ultimately depends on its output capacitor
decoupling network. This is an inherent limitation with
any DC/DC converter once the speed of the transient
exceeds its bandwidth capability. If the target application
specifies a higher di/dt or lower voltage deviation, the
requirement can only be met with additional output
capacitor decoupling. In these cases special attention
must be paid to the type, value and ESR of the capacitors
selected.

If the transient performance requirements exceed that
specified in the data sheet, or the total amount of load
capacitance is above 3,000 µF, the selection of output
capacitors becomes more important. For further guidance
consult the separate application note, “Selecting Capaci-
tors for PTH Products in High-Performance Applications.”
