The ISL6420BMAEP simplifies the implementation of a complete control and protection scheme for a highperformance DC/DC buck converter. It is designed to drive N-Channel MOSFETs in a synchronous rectified buck topology, the ISL6420BMAEP 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.
