Halogen free and RoHS compliant package
Applications
Chargers for cell/cordless phones, PDAs, MP3/portable audio
devices, adapters, etc.
Description
The LNK632DG dramatically simplies 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. The combination of
proprietary IC trimming and E-Shield transformer construction
techniques enables Clampless designs with the LNK632DG when
an external bias circuit is used.
The device incorporates a 700 V power MOSFET, a novel ON/OFF
control state machine, a high voltage switched current source for
self biasing, frequency jittering, cycle-by-cycle current limit and
hysteretic thermal shutdown circuitry onto a monolithic IC.
