48 V Three-level Synchronous Buck Converter

Overview

TopologyBuck Converter
Input voltage44-60 V
Output 119 V / 12.5 A
IC revision1.0

Description

The EPC9148 demonstration board is a 60 V maximum input voltage,12.5 A maximum output current, 19 V output voltage, ultra-thin threelevel synchronous buck converter with only 3.5 mm component height. It features the 40 V EPC2055 and the 100 V EPC2053 and EPC2038 GaN FETs and the new Würth Elektronik super thin inductor 7443762504022. The purpose of this demonstrate board is to simplify the evaluation of GaN FET-based multi-level synchronous buck converter.

Features

  • 44 – 60 VIN to 5 – 20 VOUT
  • FSW = 400 kHz, Max height < 4mm
  • Peak efficiency = 98%, Up to 12.5 A

Typical applications

  • High Performance Computing – ultra-thin laptops, high-end gaming systems
