Overview
Description
The ISL81601DEMO1Z demonstration 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 diode emulation mode (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

Hello,We are planning to connect three controllers in parallel after the demo board and control them via a microcontroller. We have a question regarding the current sharing mechanism:Can we handle the current sharing entirely within the uC by simply dividing and assigning the target current per controller (e ...
