Intersil Synchronous Step-Down PWM Controllers PWM Controller for ISL8117 for Synchronous Buck Controllers

The ISL8117 and ISL8117A are synchronous buck controllers that generate POL voltage rails and bias voltage rails for a wide variety of applications in industrial and general purpose segments. Their wide input and output voltage ranges make them suitable for telecommunication and after-market automotive applications. The ISL8117A is a derivative from the ISL8117 by replacing its CLKOUT pin with COMP pin to provide flexibility to customers to configure the voltage loop compensation externally.
