Overview

Description

The ISL81401EVAL1Z evaluation board features the ISL81401, a 40V high voltage synchronous buck-boost controller that offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protections. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimize inductor size while the strong gate driver delivers up to 20A for the buck-boost output.

Features

  • Wide input range: 6V to 40V
  • 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
  • Power-good (PGOOD) indicator
  • OVP, OTP and UVP protection
  • Back biased from output to improve efficiency
