AP3107H

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.
