Overview
Data Sheet GREEN MODE PWM CONTROLLER General Description Features AP384XG The AP384XG is a Green Mode PWM controller.
It is specially designed for off-line AC-DC adapter and battery 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.
· Green Mode PWM Controller to Support the "Blue Angel" Norm · Adjustable Skip Cycle Mode Operation · Low Start-up Current: 50μA (Typ.
) · Low Standby Operating Current: 6mA · Internal Leading Edge Blanking · Adjustable Oscillator F...
