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

by linear.com: 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 enables maximum power operation with high impedance input sources such as solar panels. An external resistor...
