EPC9178: 15 A, 30V/60V Back-to-Back Converter

Overview

TopologyBuck-Boost Converter
Input voltage30-60 V
Output 160 V / 15 A
IC revision4

Description

The EPC9178 is a 30 V – 60 V Input/Output, 15 A max back-to-back converter reference design suitable for solar optimizers. The EPC9178 features the 100 V EPC2306 eGaN® FET

Features

  • Wide input voltage range of 30 V to 60 V
  • Selectable output voltages that match most common solar panel bus voltages
  • Employs four low conduction and switching loss EPC2306 GaN FETs in back-to-back converter configuration
  • Simple, low component count, high power-density circuit design within a compact 50 x 60 mm footprint (excluding inductor)
  • Smooth transition from step up to step down or from step down to step up output voltage
  • Supports multiple inductor footprints, allowing customizing the inductor
  • Supports adding additional ceramic capacitors to input and output
  • Programmable configuration controller

Typical applications

  • Solar optimizers, Battery power systems (stabilizers, chargers, backup)
