Description

This reference design demonstrates a single-phase buck converter with integrated FETs and a very small design size. The design accepts an input voltage from 24 V_IN to 36 V_IN, and provides a regulated 3.3-V output up to 1-A continuous and 1.2-A peak. Two revisions of the board were designed and manufactured to compare the EMI and thermal performance between the two PCB layouts. Otherwise, both versions of the boards use the same exact circuitry.
