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 ...
