AP3720, CURRENT MODE PWM CONTROLLER
The AP3720 is a low startup current, current mode PWM controller with green-mode operation.
The PWM switching frequency at normal operation is 65k, but when the output power drops below the specifically level, the device enters the frequency-drop mode and the typical operating frequency is 20kHz (no
