LTC3633 Datasheet Dual Channel 3a 15v Monolithic Synchronous Step-down Regulator

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3633 is a high efficiency, dual-channel monolithic synchronous buck regulator using a controlled on-time, current mode architecture, with phase lockable switching frequency.

The two channels can run 180° out of phase, which relaxes the requirements for input and output capacitance.

The operating supply voltage range is from 3.6V to 15V, making it suitable for dual cell lithium-ion batteries as well as point of load power supply applications from a 12V or 5V supply.
