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 se...
