AP3101
GREEN MODE PWM CONTROLLER
Description
Pin Assignments
The AP3101 is a green PWM controller operating in current mode. It
is specifically 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 resistor. 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 features including
leading edge blanking, synchronized slope compensation, over-
current, over-temperature and short circuit protection.
The AP3101 is available in SO-8 package.
