180 W High Power Density GaN Buck Converter

Overview

TopologyBuck Converter
Input voltage20-36 V
Output 120 V / 14.3 A
IC revision1.0

Description

The EPC91109 evaluation board features a very compact and efficient 20–36 V to 12/16/20 V, two-phase synchronous buck converter. It uses four EPC2057, a 50 V-rated eGaN® FET, and the LTC7890, an analog two-phase step-down controller. The board can be configured as a two-phase interleaved converter with a single output, or as a dual-output buck converter.As the former, it can deliver up to 14.3 A into a 12 V load from a 36 V supply, equivalent to 180 W of input power, the maximum allowed by the USB-PD 3.1 specification for a 36 V bus. The power stage area, including the inductors, measures 24 x 24 mm; it has a maximum component height of 3 mm; and it does not require a heatsink or forced air for cooling

Features

Configurable to operate in either two-phase or single phase, dual-output modeUtilizes a small inductor of just 6.95 x 6.60 mm and 3 mm thicknessNo heatsink or airflow requiredADI’s LTC7890 100 V two-phase synchronous buck controller for GaN FETs

Typical applications

  • Automotive consoles
  • Computing, industrial, consumer, and telecom power
