Overview
Description
The ISL81401AEVAL1Z evaluation board features the ISL81401A, 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 the inductor size while the strong gate driver delivers up to 20A for the buck-boost output.
Features
- Wide input range: 6V to 40V
- 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
