LTC3544

Quad Synchronous Step-Down Regulator

LTC3544 Features

* High Efficiency: Up to 95%

* Four Independent Regulators Provide Up to 300mA, 200mA, 200mA and 100mA Output Current

* 2.25V to 5.5V Input Voltage Range

* 2.25MHz Constant-Frequency Operation

* No Schottky Diodes Required

* Extremely Low Channel-to-Channel Transient Crosstalk

LTC3544 General Description

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.
