... Chargers for cell/cordless phones, PDAs, MP3/portable audio • devices, adapters, etc. Description The LNK632DG dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry. The device uses an ON/OFF control technique to provide very tight output voltage regulation, in addition to output current control ideal for battery charging applications ...
