Preliminary Datasheet HIGH VOLTAGE GREEN MODE PWM CONTROLLER AP3107/H General Description The AP3107/H series is the high voltage start-up, current mode PWM controller with green mode power-saving operation. To minimize the standby power consumption, a proprietary adaptive green mode function provides frequency modulation at light load conditions. To avoid acoustic noise problems, the minimum PWM frequency is set at about 26kHz. The AP3107/H series features proprietary frequency dithering function internally that helps to reduce EMI emission of a power supply with minimum line filters used. The AP3107/H also integrates a lot of functions such as Leading-Edge Blanking (LEB) of the current sensing, internal slope compensation, line compensation and several protection features. The protection functions include cycle-by-cycle current limit (OCP), over voltage protection, OTP, OLP and brownout protection. The AP3107/H series is available in SOIC-7 package.

This pin is shortened to the ground to set the maximum brownout voltage Voltage Feedback Pin., Connecting it with an opto-coupler to close the control loop can achieve system regulation Current Sense Pin. Connect it to sense the MOSFET current Ground Gate drive output to drive the external MOSFET Supply Voltage Pin Connect this pin to the positive terminal of bulk capacitor to provide start-up current for the controller.
