LTC4008 Datasheet - Linear Technology

LTC4008 Multi-Chemistry Battery Charger

The LTC®4008 is a constant-current/constant-voltage charger controller. The PWM controller uses a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors. Charging current is programmable with a sense resistor and .
