Overview
Description
The ISL8115DEMO1Z is a compact reference design synchronous buck converter (28.19mm x 16.89mm) for implementing Renesas' ISL8115 wide input range PWM controller. Utilizing voltage mode control with input feed-forward, the ISL8115DEMO1Z maintains a constant loop gain for optimal transient response, especially for applications with a wide input voltage range.
