Overview

The ISL8115EVAL1Z is a synchronous buck converter evaluation board that is used to implement Renesas' ISL8115 wide input range pulse width modulation (PWM) controller. Utilizing voltage mode control with input feed-forward, this board maintains a constant loop gain for an optimal transient response, especially for applications with a wide input voltage range.
