LTC7818 Datasheet (Analog Devices) - Buck/Buck/Boost Synchronous Controller

LTC7818, Buck/Buck/Boost Synchronous Controller

The LTC®7818 is a high performance triple output (buck/ buck/boost) synchronous DC/DC switching regulator controller that drives all N-channel power MOSFET stages.

Its constant-frequency current mode architecture allows a phase-lockable switching frequency of up to 3MHz.

The LTC7818 operates from a
