High Voltage Buck-Boost Controller Evaluation Board

The ISL81601EVAL1Z and ISL81601EVAL2Z evaluation board features the ISL81601, a 60V high voltage synchronous buck-boost controller that offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protection.

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.

  • Wide input range: 9V to 60V (for ISL81601EVAL1Z)
  • Wide input range: 32V to 60V (for ISL81601EVAL2Z)
  • Bidirectional operation
  • High light-load efficiency in pulse skipping DEM operation
  • Optional DEM/PWM operation
  • Optional CC/HICCUP OCP protection
  • Supports prebias output with soft-start
  • PGOOD indicator
  • OVP, OTP, and UVP protection
  • Back biased from output to improve efficiency (for ISL81601EVAL1Z)
