LTC3544B Datasheet (Linear Technology) - Quad Synchronous Step-Down Regulator

LTC3544B, Quad Synchronous Step-Down Regulator

The LTC®3544B 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 LTC3544B well suited for single Li-Ion/polymer batt
