Gerneral Description

The WS2268 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 WS2268 provides accurate constant voltage,

constant current (CV/CC) regulation without requiring

the opto-coupler and the secondary control circuitry.

It also eliminates the need of loop compensation

circuitry while maintaining stability.

The WS2268 achieves excellent regulation and

high

power

efficiency,

the

no-load

power

consumption is less than 100mW.

The WS2268 is available in SOP8 package.
