LTC7851-1 - DC/DC Controller

Download the LTC7851-1 datasheet PDF. This datasheet also covers the LTC7851 variant, as both devices belong to the same dc/dc controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®7851/LTC7851-1 are quad output multiphase synchronous step-down switching regulator controllers that employ a constant frequency voltage mode architecture.

They maintain excellent current balance between channels when paralleled with their internal current sharing loop.
