80V Bidirectional 4-Switch Synchronous Buck-Boost Controller

Overview

TopologyBuck-Boost Converter
Input voltage32-80 V
Switching frequency100-600 kHz
Output 148 V / 10 A
IC revision1

Description

The ISL81801DEMO1Z demonstration board (shown in Figure 8) features the ISL81801, a 80V high voltage synchronous buck-boost controller that provides external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. Programmable switching frequency ranging from 100kHz to 600kHz helps to optimize the inductor size while the strong gate driver delivers up to 20A for the buck-boost output.

Features

  • Wide input range: 32V to 80V
  • Bidirectional operation
  • High light-load efficiency in pulse skipping DEM operation
  • Programmable soft-start
  • Optional DEM/PWM operation
  • Optional CC/HICCUP OCP protection
  • Supports prebias output with soft-start
  • PGOOD indicator
  • OVP, OTP, and UVP protection
  • Parallelable operation

Typical applications

  • Medical equipment
  • Robots and drones
  • Redundant power supplies
  • Security surveillance
  • Battery backup, UPS/storage systems, Battery powered industrial applications, Renewable energy
  • Building and industrial automation
