Overview

Data Sheet LOW POWER PWM CONTROLLER FOR OFF-LINE BATTERY CHARGER General Description Features AP3700E 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 skip cycle mode to reduce power consumption.
The AP3700E also features under-voltage lockout, over-current and short circuit protections.
· Current Mode Control with Skip Cycle Capability · Lower Operating Current: 0.
45mA · Fixed Switching Frequency: 60 kHz · Frequency Dithering for Low EMI: ±2.
5kHz ·...
