Overview
Description
The ISL8117AEVAL1Z demonstrates the performance of the ISL8117A synchronous step-down PWM controller. The board is configured for 18V to 60V input voltage range, with a 12V output capable of 20A. This evaluation board has multiple test points for easy probing. The QFN version of ISL8117A is used on this board.
Features
- Wide input range: 4.5V to 60V
- High light-load efficiency in pulse skipping DEM operation
- Programmable soft-start
- Optional DEM/CCM operation
- Supports prebias output with SR soft-start
- External frequency sync
- PGOOD indicator
- OCP, OVP, OTP, UVP protection
- Back biased from output to improve efficiency
- Small and compact designs
