Overview
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.
The output voltage can be precisely regulated to as low as 0.
8V, with a maximum tolerance of ±1.
5% over temperature and line voltage variations.
A fixed frequency oscillator reduces design complexity, while balancing ...
