Green-Mode Power Switch
PIN DESCRIPTION
Pin Symbol
Description
1 Source Power MOSFET Source
2
CS
Current sense. This pin senses the voltage across a resistor, to control PWM output. This pin
also provides current amplitude information for current-mode control.
3
GND Ground
4
RT This current is used to charge an internal capacitor, to determine the switching frequency.
5
COMP
Voltage feedback. The pin provides the output voltage regulation signal, it provides feedback
to the internal PWM comparator, so that the PWM comparator can control the duty cycle.
6
VCC Supply Voltage in
7
Drain Power MOSFET Drain
8
Drain Power MOSFET Drain
