LOW POWER PWM CONTROLLER FOR OFF-LINE BATTERY CHARGER

AP3700E

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.

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 AP3700E switches on and off

at a fixed switching frequency of 60 kHz. With a cur- · Low Total Cost Solution

rent limit capability of 460mA, the AP3700E can

directly drive the emitter of high voltage NPN transis-

tor. When output power falls below a given level, the

IC enters skip cycle mode to reduce power consump-

tion.

The AP3700E also features under-voltage lockout,

over-current and short circuit protections.

The AP3700E is available in TO-92 package.
