LTC7812 Datasheet (Linear Technology) - 38V Synchronous Boost+Buck Controller

LTC7812, 38V Synchronous Boost+Buck Controller

The LTC®7812 is a high performance synchronous Boost+Buck DC/DC switching regulator controller that drives all N-channel power MOSFET stages.

It contains independent step-up (boost) and step-down (buck) controllers that can regulate two separate outputs or be cascaded to regulate an output voltage f
