The LTC.7818 is a high performance triple output (buck/buck/boost) synchronous DC/DC switching regulator controllerthat drives all N-channel power MOSFET stages.
Its constant-frequency current mode architecture allowsa phase-lockable switching frequency of up to 3MHz.The LTC7818 operates from a wide 4.5V to 40V inputsupply range. When biased from the output of the boostconverter or another auxiliary supply, the LTC7818 canoperate from an input supply as low as 1V after start-up.
The LTC7818 synchronous boost PassThru capabilityminimizes losses in automotive start-stop applications.The very low no-load quiescent current extends operatingrun time in battery powered systems. OPTI-LOOP.Compensationallows the transient response to be optimizedover a wide range of output ..
