650V/800V avalanche rugged CoolMOS™
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.

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.
Drain (Drain of integrated CoolMOS™)
Pin Drain is the connection to the Drain of the internal
CoolMOSTM
.
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.

The Undervoltage Lockout monitors the external
supply voltage VVCC. In case the IC is inactive the
current consumption is max. 55µA. When the SMPS is
plugged to the main line the current through RStart-up
charges the external Capacitor CVCC. When VVCC
exceeds the on-threshold VCCon=13.5V the internal bias
circuit and the voltage reference are switched on. After
that the internal bandgap generates a reference
voltage VREF=6.5V to supply the internal circuits. To
avoid uncontrolled ringing at switch-on a hysteresis is
implemented which means that switch-off is only after
active mode when Vcc falls below 8.5V.

In case of switch-on a Power Up Reset is done by

Pulse Width Modulation
In case the amplified current sense signal exceeds the
FB signal the on-time Ton of the driver is finished by
resetting the PWM-Latch (see Figure 8).
The primary current is sensed by the external series
resistor RSense inserted in the source of the integrated
CoolMOS™. By means of Current Mode regulation, the
When VVCC falls below the off-threshold VCCoff=8.5V the

PWM-OP
The input of the PWM-OP is applied over the internal
leading edge blanking to the external sense resistor
RSense connected to pin Isense. RSense converts the
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 PWM-
Comparator, C5 and the Soft-Start-Comparator.
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 T2, the voltage source V1 and the 1st order
low pass filter composed of R1 and C1(see Figure 9,
Figure 10). Every time the oscillator shuts down for
max. duty cycle limitation the switch T2 is closed by
VOSC. When the oscillator triggers the Gate Driver T2 is
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.
3.2.2
PWM-Comparator
The PWM-Comparator compares the sensed current
signal of the integrated CoolMOSTM with the feedback
signal VFB (see Figure 11). VFB is created by an
external optocoupler or external transistor in
By means of the Comparator C5, the Gate Driver is
switched-off until the voltage ramp exceeds 0.3V. It combination with the internal pull-up resistor RFB and
allows the duty cycle to be reduced continuously till 0%
by decreasing VFB below that threshold.
provides the load information of the feedback circuitry.
When the amplified current signal of the integrated
CoolMOS™ exceeds the signal VFB the PWM-
Comparator switches off the Gate Driver.

input. When Soft-Start voltage VSoftS is less than
Feedback voltage VFB the Soft-Start-Comparator limits
the pulse width by resetting the PWM-Latch (see
Figure 12). In addition to Start-Up, Soft-Start is also
activated at each restart attempt during Auto Restart.
By means of the above mentioned CSoft-Start the Soft-
Start can be defined by the user. The Soft-Start is
finished when VSoftS exceeds 5.3V. At that time the
Protection Unit is activated by Comparator C4 and
senses the FB by Comparator C3 wether the voltage is
below 4.8V which means that the voltage on the
secondary side of the SMPS is settled. The internal
Zener Diode at SoftS has a clamp voltage of 5.6V to
prevent the internal circuit from saturation (see Figure

Sense. By means of RSense the source current is
transformed to a sense voltage VSense. When the
voltage VSense exceeds the internal threshold voltage
Vcsth the Current-Limit-Comparator immediately turns
off the gate drive. To prevent the Current Limiting from
distortions caused by leading edge spikes a Leading
Edge Blanking is integrated at the Current Sense.
Furthermore a Propagation Delay Compensation is
added to support the immediate shut down of the
CoolMOS™ in case of overcurrent.

Leading Edge Blanking
The oscillator generates a frequency fswitch = 67kHz/
100kHz. A resistor, a capacitor and a current source
and current sink which determine the frequency are
integrated. The charging and discharging current of the
implemented oscillator capacitor are internally
trimmed, in order to achieve a very accurate switching
frequency. The ratio of controlled charge to discharge
current is adjusted to reach a max. duty cycle limitation
of Dmax=0.72.

Frequency Reduction
The frequency of the oscillator is depending on the
voltage at pin FB. The dependence is shown in Figure
15. This feature allows a power supply to operate at
lower frequency at light loads thus lowering the
switching losses while maintaining good cross
regulation performance and low output ripple. In case
of low power the power consumption of the whole
SMPS can now be reduced very effective. The minimal
reachable frequency is limited to 20kHz/21.5 kHz to
avoid audible noise in any case.

Each time when CoolMOS™ is switched on a leading

means of a dynamic threshold voltage Vcsth (see Figure
18). In case of a steeper slope the switch off of the
driver is earlier to compensate the delay.
3.5.2
Propagation Delay Compensation
E.g. Ipeak = 0.5A with RSense = 2. Without propagation
delay compensation the current sense threshold is set
to a static voltage level Vcsth=1V. A current ramp of
dI/dt = 0.4A/µs, that means dVSense/dt = 0.8V/µs, and a
propagation delay time of i.e. tPropagation Delay =180ns
leads then to a Ipeak overshoot of 12%. By means of
propagation delay compensation the overshoot is only
about 2% (see Figure 19).
In case of overcurrent detection by ILimit the shut down
of CoolMOS™ 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 17).

The overshoot of Signal2 is bigger than of Signal1 due
to the steeper rising waveform.
A propagation delay compensation is integrated to
bound the overshoot dependent 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 CoolMOS™ is compensated
over temperature within a range of at least.

The oscillator clock output applies a set pulse to the

The driver-stage drives the gate of the CoolMOS™ and
is optimized to minimize EMI and to provide high circuit
efficiency. This is done by reducing the switch on slope
when reaching the CoolMOS™ threshold. This is
achieved by a slope control of the rising edge at the
driver’s output (see Figure 20) to the CoolMOS™ gate.

Thus the leading switch on spike is minimized. When
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. At voltages below the undervoltage lockout
threshold VVCCoff the gate drive is active low.

thermal shutdown is latched by the Error-Latch. In case
of those failure modes the Error-Latch is set after a

Figure 21 shows the Auto Restart Mode in case of

detection is activated by C4 when the voltage at pin
SoftS exceeds 5.3V. Till this time the IC operates in the
Soft-Start Phase. After this phase the comparator C3
can set the Error-Latch in case of open loop or overload
which leads the feedback voltage VFB to exceed the
threshold of 4.8V. After latching VCC decreases till
8.5V and inactivates the IC. At this time the external
Soft-Start capacitor is discharged by the internal
