Data Sheet  
LOW POWER PWM CONTROLLER FOR OFF-LINE BATTERY CHARGER  
AP3700/A  
General Description  
Features  
The AP3700/A is a green-mode pulse width modula-  
tion (PWM) controller. It is specially designed for low  
power applications such as off-line battery chargers,  
where the needs for low standby power, space saving  
and low cost are all required. In a battery charger rated  
5V/1A, the maximum standby power is only 0.18W.

Current Mode Control with Skip Cycle Capability  
Lower Operating Current: 0.45mA  
Fixed Switching Frequency: 60 kHz  
Frequency Dithering for Low EMI: ±2.5kHz  
Under-Voltage Lockout Protection  
Over-Current Protection  
Internal Short Circuit Protection  
Higher Output Voltage at OUT Terminal  
In normal operation, the AP3700/A switches on and  
off at a fixed switching frequency of 60 kHz. With a  
current limit capability of 460mA for AP3700 and · Low Total Cost Solution  
500mA for AP3700A, the AP3700/A can directly  
drive the emitter of high voltage NPN transistor. When  
output power falls below a given level, the IC enters  
skip cycle mode to reduce power consumption.

Battery Chargers  
Off-Line Power Supplies  
The AP3700/A also features under-voltage lockout,  
over-current and short circuit protections.  
The AP3700/A is available in TO-92 package.
