Description
The second generation CoolSET™-F2 provides several
special enhancements to satisfy the needs for low power
standby and protection features. In standby mode
frequency reduction is used to lower the power
consumption and support a stable output voltage in this
mode. The frequency reduction is limited to 20kHz/21.5
kHz to avoid audible noise. In case of failure modes like
open loop, overvoltage or overload due to short circuit the
device switches in Auto Restart Mode which is controlled by
the internal protection unit. By means of the internal precise
peak current limitation, the dimension of the transformer
and the secondary diode can be sized lower which leads to
more cost effective for the overall system.

1.5 Pin Functionality
SoftS (Soft Start & Auto Restart Control)
This pin combines the function of Soft Start in case of
Start Up and Auto Restart Mode and the controlling of
the Auto Restart Mode in case of an error detection.
FB (Feedback)
The information about the regulation is provided by the
FB Pin to the internal Protection Unit and to the internal
PWM-Comparator to control the duty cycle.
Isense (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated CoolMOS™. When Isense reaches the
internal threshold of the Current Limit Comparator, the
Driver output is disabled. By this means the Over
Current Detection is realized.
Furthermore the current information is provided for the
PWM-Comparator to realize the Current Mode.
CoolSET™-F2
Pin Configuration and Functionality
Drain (Drain of integrated CoolMOS™)
Pin Drain is the connection to the Drain of the internal
CoolMOS
VCC (Power supply)
This pin is the positive supply of the IC. The operating
range is between 8.5V and 21V.
To provide overvoltage protection the driver gets
disabled when the voltage becomes higher than 16.5V
during Start Up Phase.
GND (Ground)
This pin is the ground of the primary side of the SMPS.

implemented which means that switch-off is only after

In case the amplified current sense signal exceeds the
FB signal the on-time T
of the driver is finished by
on
resetting the PWM-Latch (see Figure 8).
The primary current is sensed by the external series
resistor R
inserted in the source of the integrated
Sense
t
CoolMOS™. By means of Current Mode regulation, the

secondary output voltage is insensitive on line
variations. Line variation changes the current
waveform slope which controls the duty cycle.

Figure 9 Improved Current Mode
To improve the Current Mode during light load
conditions the amplified current ramp of the PWM-OP
is superimposed on a voltage ramp, which is built by
the switch T
low pass filter composed of R
Figure 10). Every time the oscillator shuts down for
max. duty cycle limitation the switch T2 is closed by
V
. When the oscillator triggers the Gate Driver T2 is
OSC
opened so that the voltage ramp can start.
In case of light load the amplified current ramp is to
small to ensure a stable regulation. In that case the
Voltage Ramp is a well defined signal for the
comparison with the FB-signal. The duty cycle is then
controlled by the slope of the Voltage Ramp.
By means of the Comparator C5, the Gate Driver is
switched-off until the voltage ramp exceeds 0.3V. It
allows the duty cycle to be reduced continuously till 0%
by decreasing V
, the voltage source V1 and the 1st order

below that threshold.

3.2.1 PWM-OP
The input of the PWM-OP is applied over the internal
leading edge blanking to the external sense resistor
R
connected to pin Isense. R
Sense
converts the
Sense
source current into a sense voltage. The sense voltage
is amplified with a gain of 3.65 by PWM OP. The output
of the PWM-OP is connected to the voltage source V1.
The voltage ramp with the superimposed amplified
current signal is fed into the positive inputs of the PWMComparator, C5 and the Soft-Start-Comparator.
3.2.2 PWM-Comparator
The PWM-Comparator compares the sensed current
signal of the integrated CoolMOS
signal V
(see Figure 11). VFB is created by an
FB
external optocoupler or external transistor in
combination with the internal pull-up resistor R
provides the load information of the feedback circuitry.
