Source Power MOSFET Source
Current sense. This pin senses the voltage across a resistor, to control PWM output. This pin
CS
also provides current amplitude information for current-mode control.
GND Ground
RT
This current is used to charge an internal capacitor, to determine the switching frequency.
Voltage feedback. The pin provides the output voltage regulation signal, it provides feedback
COMP
to the internal PWM comparator, so that the PWM comparator can control the duty cycle.
