LOW POWER PWM CONTROLLER FOR OFF-LINE BATTERY CHARGER
General Description
Features
AP3700/A
The AP3700/A is a green-mode pulse width modulation (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.
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 500mA for AP3700A, the AP3700/A can directly drive the emitter of high voltage
NPN transistor.
When output power falls below ...
