Advanced Single Synchronous Buck Pulse-Width Modulation (PWM) Controller
The ISL6420 makes simple work out of implementing a complete control and protection scheme for a high-performance DC/DC buck converter. Designed to drive N-channel MOSFETs in a synchronous rectified buck topology, the ISL6420 integrates control, output adjustment, monitoring and protection functions into a single package. Additionally, the IC features an external reference voltage tracking mode for externally referenced buck converter applications and DDR termination supplies, as well as a voltage margining mode for system testing in networking DC/DC converter applications.
