ISL6439 Datasheet (Intersil) - Single Sync Buck PWM Controller

ISL6439, Single Sync Buck PWM Controller

Data Sheet Single Sync Buck PWM Controller for Broadband Gateway Applications The ISL6439 makes easy work out of implementing a complete control and protection scheme for a DC/DC step-down converter.

Designed to drive N-Channel MOSFETs in a synchronous buck topology, the ISL6439 integrates the control, output adjustment, monitoring and protection functions into a single package.

The ISL6439 provides simple, single feedback loop, voltagemode control with fast transient response.
