AP3703 Datasheet Low-power Off-line Primary Side Regulation Controller

Manufacturer: BCD Semiconductor Manufacturing Limited

Overview: .. Preliminary Datasheet LOW-POWER OFF-LINE PRIMARY SIDE REGULATION CONTROLLER AP3703.

General Description

The AP3703 is a high performance AC/DC power supply controller for battery charger and adapter applications.

The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies.

The AP3703 provides accurate constant voltage, constant current (CV/CC) regulation while removing the opto-coupler and secondary control circuitry.

Key Features

  • Primary Side Control for Rectangular Constant Current and Constant Voltage Output Secondary CV/CC Control Circuitry Eliminating Opto-Coupler No Need for Control Loop Compensation Circuitry Flyback Topology in DCM Operation Random Frequency Modulation to Reduce System EMI Built-in Soft Start Open Feedback Protection Over Voltage Protection Short Circuit Protection Small SOT-23-5 package to achieve compact size and less component Applica.
