Preliminary Datasheet

LOW-POWER OFF-LINE PRIMARY SIDE REGULATION CONTROLLER AP3768

General Description

Features

The AP3768 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 Eliminating Opto-cou-

pler and Secondary CV/CC Control Circuitry

30mW No-load Input Power

Programmable Output Cable Voltage Drop Com-

pensation

Proprietary CC Tightening Technique to Achieve

Vertical CC Profile

Compensation for External Component Tempera-

ture Variations

Flyback Topology in DCM Operation

Random Frequency Adjustment to Reduce Sys-

tem EMI

Built-in Soft Start

Over Voltage Protection

Short Circuit Protection

SOIC-8 Package

The AP3768 provides accurate constant voltage, con-

stant current (CV/CC) regulation without requiring an

opto-coupler and secondary control circuitry. It also

eliminates the need of loop compensation circuitry

while maintaining stability. The AP3768 achieves

excellent regulation and high average efficiency, yet

meets the requirement for no-load consumption less

than 30mW.

The AP3768 has the built-in programmable cable volt-

age drop compensation function, which make it flexi-

ble to accommodate various cables with different

gauges and lengths.

Applications

The AP3768 is available in SOIC-8 package.

Adapter/Chargers for Cell/Cordless Phones,

PDAs, MP3 and Other Portable Apparatus

LED Driver

Standby and Auxiliary Power Supplies
