RDK-201: 6W, 5V @ 1.2A, 90 ~ 265VAC

Summary

The schematic in Figure 2 shows an adapter design using the LNK625PG that provides very tight constant voltage (CV) performance. The circuit is designed to operate from 90 VAC to 265 VAC input, with an output voltage of 5 V providing a maximum load current of 1.2 A. It consumes very little standby power and uses no Y-Capacitor to meet stringent EMI requirements. The adapter also meets and exceeds both CEC and Energy Star 2.0 regulations.

The LinkSwitch-CV family of devices has been developed to cost effectively replace all existing solutions in low power adapter applications. It is optimized for constant voltage (CV) adapter applications while using minimal external parts including the complete elimination of the optocoupler and shunt regulator.
