Data Sheet  
GREEN MODE PWM CONTROLLER  
AP384XG  
General Description  
Features  
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.

Adjustable Skip Cycle Mode Operation  
Low Start-up Current: 50μA (Typ.)  
Low Standby Operating Current: 6mA  
Internal Leading Edge Blanking  
Adjustable Oscillator Frequency up to 500KHz  
Totem Pole Output  
In normal operation, the AP384XG features adjustable  
frequency by using an external resistor and capacitor  
Under Voltage Lock Out (UVLO)  
combination. When output power falls below a given · Over-Temperature Protection  
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.  
·
Pin to Pin Replacement for AZ384XA  
Applications  
The AP384XG provides accurate protection against  
over-temperature, over-current and maximal output  
power.
