LTC3822 Datasheet (Linear Technology) - Synchronous Step-Down DC/DC Controller

LTC3822, Synchronous Step-Down DC/DC Controller

The LTC®3822 is a synchronous step-down switching regulator controller that drives external N-channel power MOSFETs using few external components.

The constant frequency current mode architecture with MOSFET VDS sensing eliminates the need for sense resistors and improves efﬁciency.
