Data Sheet
LOW POWER PWM CONTROLLER FOR OFF-LINE BATTERY CHARGER
General Description
Features
The AP3700E 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/0.8A, the maximum standby power is only 0.18Watt.
In normal operation, the AP3700E switches on and off at a fixed switching frequency of 60 kHz. With a current limit capability of 460mA, the AP3700E can directly drive the emitter of high voltage NPN transistor. When output power falls below a given level, the IC enters...
