Green-Mode PWM Controller
Description
OUT
VCC
NC
Gate driver output to drive the external MOSFET
Supply Voltage in
Unconnected pin
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.
This current is used to charge an internal capacitor, to determine the switching frequency.
Unconnected pin
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.
