LNK4002S
Description
The LinkSwitchTM-4 family of ICs dramatically simplifies low power CV/CC charger design by eliminating an optocoupler and secondary control circuitry.
Key Features
- Dynamic base drive technology provides flexibility in choice of BJT
- Extends RBSOA of BJT
- Dramatically reduces sensitivity to BJT gain
- pensates for input line voltage variations
- pensates for cable voltage drop
Applications
- Chargers for cell/cordless phones, PDAs, MP3/portable audio
