General Description
The WS2585 is a high performance AC/DC power supply
converter for battery charger and adapter applications.
The device uses Pulse Frequency Modulation (PFM)
method to build discontinuous conduction mode (DCM)
flyback power supplies. The WS2585 provides accurate
constant voltage and constant current (CC/CV) regulation
without requiring the opto-coupler and the secondary control
circuitry.
It also eliminates the need of loop compensation circuitry
while maintaining stability.
The WS2585 achieves excellent regulation and high power
efficiency, the no-load power consumption is less than
100mW.
The WS2585 is available in DIP8 package.
