LTC3633 Datasheet (Linear Technology) - Dual Channel 3A 15V Monolithic Synchronous Step-Down Regulator

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.
