Power Integrations LNK603DG, Off line Power Switch IC 7-Pin, SOIC

The LinkSwitch-II dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry. The device introduces a revolutionary control technique to provide very tight output voltage and current regulation, compensating for transformer and internal parameter tolerances along with input voltage variations.,

Easily meets all global energy efficiency regulations
No-load consumption <200 mW at 230 VAC and down to below 30 mW with optional external bias
On/Off control provides constant efficiency down to very light loads – ideal for CEC and ENERGY STAR 2.0 regulations
No current sense resistors – maximizes efficiency
