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.
