GREEN MODE PWM CONTROLLER AP3101
Preliminary Datasheet

BCD Semiconductor Manufacturing Limited
General Description
The AP3101 is a green PWM controller operating in
current mode. It is specially designed for off-line AC-
DC adapter and battery charger applications where the
needs for low standby power and better protection
function are increasing.
The AP3101 features adjustable oscillator frequency in
normal operation, which is done by an external resis-
tor. It automatically switches to skip cycle mode when
output power drops below a given level. The IC also
features low start-up and operation current for its
BiCMOS process.
The AP3101 provides comprehensive protection fea-
tures including leading edge blanking, synchronized
slope compensation, over-current, over-temperature
and short circuit protection.
The AP3101 is available in 2 packages: SOIC-8 and
DIP-8.
