LTC7851 Datasheet (Analog Devices)

LTC7851, DC/DC Controller

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.
