Data Sheet 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 a given level, the IC enters skip cycle mode to reduce power consumption.
