Data Sheet
GREEN MODE PWM CONTROLLER
General Description
The AP384XG is a Green Mode PWM controller. It is
specially designed for off-line AC-DC adapter and bat-
tery charger applications where both needs for low
standby power and high efficiency in normal operation
are required. In a well designed product, the AP384XG
is capable to allow the system consuming only 0.5W
power in standby mode.
In normal operation, the AP384XG features adjustable
frequency by using an external resistor and capacitor
combination. When output power falls below a given
level, the IC automatically switches to the skip mode,
which works by skipping switching cycles. The
AP384XG also features low start-up and low standby
operating current for its special topology.
The AP384XG provides accurate protection against
over-temperature, over-current and maximal output
power.
The AP384XG is available in SOIC-8 and DIP-8
packages.
