LTC3633 - Linear Technology

LTC3633 Dual Channel 3A 15V Monolithic Synchronous Step-Down Regulator

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 sui.
