3.3.1
The input of the PWM-OP is applied over the internal
leading edge blanking to the external sense resistor
R
current into a sense voltage. The sense voltage is
amplified with a gain of 3.3 by PWM OP. The output of
the PWM-OP is connected to the voltage source V
The voltage ramp with the superimposed amplified
current signal is fed into the positive inputs of the PWM-
Comparator C8 and the Soft-Start-Comparator (see
Figure 6).
3.3.2
The PWM-Comparator compares the sensed current
signal of the integrated CoolMOS
signal V
optocoupler or external transistor in combination with
the internal pull-up resistor R
information of the feedback circuitry. When the
amplified current signal of the integrated CoolMOS
exceeds the signal V
off the Gate Driver.
