Introduction
Output voltage tracking and margining are two increasingly popular features in power supply designs for high performance server, ASIC and memory systems. These two functions are among the advanced features provided in the LTC3770, a wide operating range, high accuracy, synchronous step-down DC/DC controller. The LTC3770 operates with input voltages from 4V to 32V, generating output voltages down to 0.6V ...
