LTC3605 - 5A Synchronous Step-Down Regulator

General Description

The LTC®3605 is a high efficiency, monolithic synchronous buck regulator using a phase lockable controlled on-time constant frequency, current mode architecture.

PolyPhase operation allows multiple LTC3605 regulators to run out of phase while using minimal input and output capacitance.
