The LP3946 is a stand-alone single cell Li-Ion charger with an integrated pass transistor and current sense resistor. In addition to its charging function, it can be used in low dropout (LDO) mode.

Charging a battery using the constant-current/constant-voltage (CC/CV) method involves using the constant current in the initial state of charging and then switching ...

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...
