LTC3672B-2 Datasheet (Linear Technology) - Monolithic Fixed-Output 400mA Buck Regulator

LTC3672B-2, Monolithic Fixed-Output 400mA Buck Regulator

The LTC®3672B-2 is a triple power supply composed of a 400mA synchronous buck regulator and two 150mA low-dropout linear regulators (LDOs).

Constant-frequency 2.25MHz operation is maintained down to very light loads.

The input supply range of 2.9V to 5.5V is especially wellsuited for single-cell Lit
