Overview
Description
The ISL81601EVAL2Z evaluation board features the ISL81601, a 60V high voltage synchronous buck-boost controller that offers external soft-start and 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: 32V to 60V
- 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
- Power-good (PGOOD) indicator
- OVP, OTP and UVP protection
