Description
General part information
LT8551 Series
The LT8551 is a multiphase expander for synchronous boost DC/DC converters. It operates in tandem with any synchronous boost DC/DC converter to increase the load current capability by adding additional phases, which are clocked out-of-phase to reduce ripple current and filtering capacitance. It easily adds phases without the need to route sensitive feedback and control signals.The LT8551 integrates 5V gate drivers and can support up to four boost phases per device. Multiple LT8551 devices can be used for up to 18 phases. It accurately monitors and adjusts the current of each channel to achieve excellent DC and transient current sharing.The LT8551 operates over a fixed frequency from 100kHz to 1MHz or can be synchronized to an external clock.ApplicationsHigh Current Distributed Power SystemsTelecom, Datacom, and Storage SystemsIndustrial and Automotive
