PRIMARY SIDE CONTROL IC FOR OFF-LINE BATTERY CHARGERS AP3706

General Description

Features

The AP3706 is a high performance AC/DC power sup-

ply controller for battery charger and adapter applica-

tions. The device uses Pulse Frequency Modulation

(PFM) method to build discontinuous conduction

mode (DCM) flyback power supplies.

Primary Side Control for Rectangular Constant

Current and Constant Voltage Output

Eliminates Opto-Coupler and Secondary CV/CC

Control Circuitry

Eliminates Control Loop Compensation Circuitry

Flyback Topology in DCM Operation

Random Frequency Modulation to Reduce

System EMI

Valley Turn on of External Power NPN Transistor

Built-in Soft Start

Open Circuit Protection

The AP3706 provides constant voltage, constant cur-

rent (CV/CC) regulation without requiring an opto-

coupler and secondary control circuitry. It also elimi-

nates the need of loop compensation circuitry while

maintaining stability.

The AP3706 achieves excellent regulation and high · Over Voltage Protection

power efficiency, the no-load power consumption is

less than 200mW at 265VAC input.

Short Circuit Protection

Applications

The AP3706 is available in SOIC-8 and DIP-8 pack-

ages.

Adapters/Chargers for Cell/Cordless Phones,

PDAs, MP3 and Other Portable Apparatus

Standby and Auxiliary Power Supplies

SOIC-8

DIP-8
