Description
Features
The new generation CoolSET™-F3 provides Active Burst
Mode to reach the lowest Standby Power Requirements
<100mW at no load. As the controller is always active
during Active Burst Mode, there is an immediate response
on load jumps without any black out in the SMPS. In Active
Burst Mode the ripple of the output voltage can be reduced
<1%. Furthermore, to increase the robustness and safety
of the system, the device enters into Auto Restart Mode in
the cases of Overtemperature, VCC Overvoltage, Output
Open Loop or Overload and VCC Undervoltage. By means
of the internal precise peak current limitation, the
dimension of the transformer and the secondary diode can
be lowered which leads to more cost efficiency. An
adjustable blanking window prevents the IC from entering
Auto Restart or Active Burst Mode unintentionally during
high load jumps. The CoolSET™-F3 family consists a wide
power class range of products for various applications.

Pin Functionality
SoftS (Soft Start & Auto Restart Control)
The SoftS pin combines the functions of Soft Start
during Start Up and error detection for Auto Restart
Mode. These functions are implemented and can be
adjusted by means of an external capacitor at SoftS to
ground. This capacitor also provides an adjustable
blanking window for high load jumps, before the IC
enters into Auto Restart Mode.
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. The FB-
Signal controls in case of light load the Active Burst
Mode of the controller.
CS (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated Depl-CoolMOS™. If CS reaches the internal
threshold of the Current Limit Comparator, the Driver
output is immediately switched off. Furthermore the
current information is provided for the PWM-
Comparator to realize the Current Mode.
Drain (Drain of integrated Depl-CoolMOS™)
Pin Drain is the connection to the Drain of the internal
Depl-CoolMOSTM
.
VCC (Power supply)
The VCC pin is the positive supply of the IC. The
operating range is between 8.5V and 21V.
GND (Ground)
The GND pin is the ground of the controller.

Introduction
CoolSET™-F3 is the further development of the
CoolSET™-F2 to meet the requirements for the lowest
Standby Power at minimum load and no load
conditions. A new fully integrated Standby Power
concept is implemented into the IC in order to keep the
application design easy. Compared to CoolSET™-F2
no further external parts are needed to achieve the
lowest Standby Power. An intelligent Active Burst
Mode is used for this Standby Mode. After entering this
mode there is still a full control of the power conversion
by the secondary side via the same optocoupler that is
used for the normal PWM control. The response on
load jumps is optimized. The voltage ripple on Vout is
minimized. Vout is further on well controlled in this
mode.

Furthermore a high voltage Startup Cell is integrated
into the IC which is switched off once the Undervoltage
Lockout on-threshold of 15V is exceeded. This Startup
Cell is part of the integrated Depl-CoolMOS™. The
external startup resistor is no longer necessary as this
Startup Cell is connected to the Drain. Power losses
are therefore reduced. This increases the efficiency
under light load conditions drastically.

Figure 6
The Undervoltage Lockout monitors the external
supply voltage VVCC. When the SMPS is plugged to the
main line the internal Startup Cell is biased and starts
to charge the external capacitor CVCC which is
connected to the VCC pin. This VCC charge current
which is provided by the Startup Cell from the Drain pin
is 1.05mA. When VVCC exceeds the on-threshold
VCCon=15V the internal voltage reference and bias
circuit are switched on. Then the Startup Cell is
switched off by the Undervoltage Lockout and therefore
no power losses present due to the connection of the
Startup Cell to the Drain voltage. To avoid uncontrolled
ringing at switch-on a hysteresis is implemented. The
switch-off of the controller can only take place after
Active Mode was entered and VVCC falls below 8.5V.
The Soft-Start capacitor is also used for providing an
adjustable blanking window for high load jumps. During
this time window the overload detection is disabled.
With this concept no further external components are
necessary to adjust the blanking window.
An Auto Restart Mode is implemented in the IC to
reduce the average power conversion in the event of
malfunction or unsafe operating condition in the SMPS
system. This feature increases the system’s
robustness and safety which would otherwise lead to a
destruction of the SMPS. Once the malfunction is
removed, normal operation is automatically initiated
after the next Start Up Phase.
The maximum current consumption before the
controller is activated is about 160µA.
The internal precise peak current limitation reduces the
costs for the transformer and the secondary diode. The
influence of the change in the input voltage on the
power limitation can be avoided together with the

Therefore the maximum power is nearly independent

SMPS. There is no need for an extra over-sizing of the

The internal Voltage Reference is switched off if Auto
Restart Mode is entered. The current consumption is
then reduced to 300µA.

By means of this extra charge stage, there is no delay
in the beginning of the Startup Phase when there is still
no switching. Furthermore Soft Start is finished at 4V to
have faster the maximum power capability. The duty
cycles DC1 and DC2 are depending on the mains and
the primary inductance of the transformer. The
limitation of the primary current by DC2 is related to
VSoftS = 4V. But DC1 is related to a maximum primary
current which is limited by the internal Current Limiting
with CS = 1V. Therefore the maximum Startup Phase
is divided into a Soft Start Phase until t1 and a phase
from t1 until t2 where maximum power is provided if
demanded by the FB signal.

At the beginning of the Startup Phase, the IC provides

capacitor CSofts in combination with the internal pull up
resistor RSoftS, determines the duty cycle until VSoftS

When the Soft Start begins, CSoftS is immediately
charged up to approx. 1V by T2. Therefore the Soft
Start Phase takes place between 1V and 4V. Above
VSoftsS = 4V there is no longer duty cycle limitation

Gate Rising Slope
Thus the leading switch on spike is minimized. When
the integrated CoolMOS™ is switched off, the falling
shape of the driver is slowed down when reaching 2V
to prevent an overshoot below ground. Furthermore the
driver circuit is designed to eliminate cross conduction
of the output stage. During powerup when VCC is
below the undervoltage lockout threshold VVCCoff, the
output of the Gate Driver is low to disable power
transfer to the seconding side.

Propagation Delay Compensation
In case of overcurrent detection, the switch-off of the
external Power Switch is delayed due to the
propagation delay of the circuit. This delay causes an
overshoot of the peak current Ipeak which depends on
the ratio of dI/dt of the peak current (see Figure 13).
Figure 12
There is a cycle by cycle Current Limiting realized by
the Current-Limit comparator C10 to provide an
overcurrent detection. The source current of the
external Power Switch is sensed via an external sense
resistor RSense . By means of RSense the source current
is transformed to a sense voltage VSense which is fed
into the pin CS. If the voltage VSense exceeds the
internal threshold voltage Vcsth the comparator C10
immediately turns off the gate drive by resetting the
PWM Latch FF1. A Propagation Delay Compensation
is added to support the immediate shut down without
delay of the Power Switch in case of Current Limiting.
The influence of the AC input voltage on the maximum
output power can thereby be avoided.

Current Limiting
The output of comparator C12 is activated by the Gate
G10 if Active Burst Mode is entered. Once activated the
current limiting is thereby reduced to 0.257V. This
voltage level determines the power level when the
Active Burst Mode is left if there is a higher power
demand.
The overshoot of Signal2 is bigger than of Signal1 due
to the steeper rising waveform. This change in the
slope is depending on the AC input voltage.
Propagation Delay Compensation is integrated to limit
the overshoot dependency on dI/dt of the rising primary
current. That means the propagation delay time
between exceeding the current sense threshold Vcsth
and the switch off of the external Power Switch is
compensated over temperature within a wide range.

to be charged starting from the clamped voltage level
at 4.4V in normal operating mode. If VSoftS exceeds
5.4V the comparator C3 releases the gate G6 to enter
the Active Burst Mode. The time window that is
generated by combining the FB and SoftS signals with
gate G6 avoids a sudden entering of the Active Burst

during this charging time of the external capacitor

significantly the efficiency at light load conditions while
supporting a low ripple on VOUT and fast response on
load jumps. During Active Burst Mode which is
controlled only by the FB signal the IC is always active
and can therefore immediately response on fast
changes at the FB signal. The Startup Cell is kept
switched off to avoid increased power losses for the
self supply.
After entering Active Burst Mode a burst flag is set and
the internal bias is switched off in order to reduce the
current consumption of the IC down to approx. 1.05mA.
In this Off State Phase the IC is no longer self supplied
so that therefore CVCC has to provide the VCC current
(see Figure 18). Furthermore gate G11 is then released
to start the next burst cycle once VFB has 3.4V
exceeded.
It has to be ensured by the application that the VCC
remains above the Undervoltage Lockout Level of 8.5V
to avoid that the Startup Cell is accidentally switched
on. Otherwise power losses are significantly increased.
The minimum VCC level during Active Burst Mode is

After entering the Active Burst Mode the FB voltage
rises as VOUT starts to decrease due to the inactive
PWM section. Comparator C6a observes the FB signal
if the voltage level 4V is exceeded. In that case the
internal circuit is again activated by the internal Bias to
start with switching. As now in Active Burst Mode the
gate G10 is released the current limit is only 0.257V to
reduce the conduction losses and to avoid audible
noise. If the load at VOUT is still below the starting level
for the Active Burst Mode the FB signal decreases
down to 3.4V. At this level C6b deactivates again the
internal circuit by switching off the internal Bias. The
gate G11 is released as after entering Active Burst
Mode the burst flag is set. If working in Active Burst
Mode the FB voltage is changing like a saw tooth
between 3.4V and 4V (see Figure 18).

The VCC voltage is observed by comparator C1 if 17V
is exceeded. The output of C1 is combined with both
the output of C11 which checks for SoftS<4.0V, and the
output of C4 which checks for FB>4.8V. Therefore the
overvoltage detection is can only active during Soft
Start Phase(SoftS<4.0V) and when FB signal is
outside the operating range > 4.8V. Therefore any
small voltage overshoots of VVCC during normal
operating cannot trigger the Auto Restart Mode.

The other fault detection which can result in the Auto

CoolSET™-F3
Functional Description
Once the Auto Restart Mode is entered, the internal
Voltage Reference is switched off in order to reduce the
current consumption of the IC as much as possible. In
this mode, the average current consumption is only
300µA as the only working block is the Undervoltage
Lockout(UVLO) which controls the Startup Cell by
switching on/off at VVCCon/VVCCoff
.
As there is no longer a self supply by the auxiliary
winding, VCC starts to drop. The UVLO switches on the
integrated Startup Cell when VCC falls below 8.5V. It
will continue to charge VCC up to 15V whereby it is
switched off again and the IC enters into the Start Up
Phase.
As long as all fault conditions have been removed, the
IC will automatically power up as usual with switching
cycle at the GATE output after Soft Start duration. Thus
the name Auto Restart Mode.
Other fault detections which are active in normal
operation is the sensing for Overload, Open Loop and
VCC undervoltage conditions. In the first 2 cases, FB
will rise above 4.8V which will be observed by C4. At
this time, S1 is released such that VSoftS can rise from
its earlier clamp voltage of 4.4V. If VSoftS exceeds 5.4V
which is observed by C3, Auto Restart Mode is entered
as both inputs of the gate G5 are high.
This charging of the Soft Start capacitor from 4.4V to
5.4V defines a blanking window which prevents the
system from entering into Auto Restart Mode un-
intentionally during large load jumps. In this event, FB
will rise close to 6.5V for a short duration before the
loop regulates with FB less than 4.8V. This is the same
blanking time window as for the Active Burst Mode and
can therefore be adjusted by the external CSoftS
.
In the case of VCC undervoltage, ie. VCC falls below
8.5V, the IC will be turn off with the Startup Cell
charging VCC as described earlier in this section. Once
VCC is charged above 15V, the IC will start a new
startup cycle. The same procedure applies when the
system is under Short Optocoupler fault condition, as it
will lead to VCC undervoltage.
