AP384XG
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.
