LT LTC3859ALEUHF#TRPBF

降压，升压/降压降压，降压升压，SEPIC4.5V ~ 38V

Overview

The LTC3859ALEUHF#PBF is a high performance triple output (buck/buck/boost) synchronous DC/DC switching regulator controller that drives all N-channel power MOSFET stages. Constant frequency current mode architecture allows a phase-lockable switching frequency of up to 850kHz. The LTC3859ALEUHF#PBF operates from a wide 4.5V to 38V input supply range. When biased from the output of the boost converter or another auxiliary supply, the LTC3859ALEUHF#PBF can operate from an input supply as low as 2.5V after start-up.

Compared to the LTC3859 and the LTC3859A, the LTC3859ALEUHF#PBF is fully pin-compatible, but with lower Burst Mode operation IQ (28μA with one channel on).
