LTC3544 Datasheet (Linear Technology) - Quad Synchronous Step-Down Regulator

LTC3544, Quad Synchronous Step-Down Regulator

The LTC®3544 is a quad, high efficiency, monolithic synchronous buck regulator using a constant-frequency, current mode architecture.

The four regulators operate independently with separate run pins.

The 2.25V to 5.5V input voltage range makes the LTC3544 well suited for single Li-Ion/polymer batter
