Quarter Brick Dual Phase Synchronous Buck Converter Automotive Reference Design
Description
PMP20659 is a dual-phase synchronous buck converter reference design utilizing the LM25119-Q1 dual synchronous buck controller I.C. The design accepts an input voltage of 4.5V to 40V and provides a 5V output capable of supplying 45A of current to the load. This represents a power density design of 225W in a quarter brick footprint. The maximum component height is set by the Coilcraft XAL1510-472 inductors at 0.394 in.
