Description
General part information
LT8550 Series
The LT8550 is a multiphase expander for synchronous buck DC/DC converters. It operates in tandem with any buck DC/DC converter to increase the load current capability by adding additional phases, which are clocked outof-phase to reduce ripple current and filtering capacitance. It easily adds phases without the need to route sensitive feedback and control signals.The LT8550 integrates gate drivers and can support up to four buck phases per device. Multiple LT8550’s 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 LT8550 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
