LTC3633A-2 Datasheet (Linear) - 20V Monolithic Synchronous Step-Down Regulator

LTC3633A-2, 20V Monolithic Synchronous Step-Down Regulator

The LTC®3633A-2 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 to relax the requirements for input and output capacitance.
