LTC4121-4.2, LTC4121 Datasheet - Linear Technology

LTC4121-4.2 40V 400mA Synchronous Step-Down Battery Charger

The LTC®4121 is a 400mA constant-current/constantvoltage (CC/CV) synchronous step-down battery charger. In addition to CC/CV operation, the LTC4121 regulates its input voltage to a programmable percentage of the input open-circuit voltage. This technique maintains maximum power transfer with high im.
