  advertisement High Accuracy Synchronous Step-Down Controller Provides
  Output Tracking and Programmable Margining – Design Note 364
  Charlie Zhao
  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 LTC В®3770, 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 with
  its highly accurate В±0.67% 0.6V reference voltage. It
  has a constant on-time, valley current mode control
  architecture, which allows the LTC3770 to operate at
  very low duty cycles with fast transient response. The
  current sensing resistor is optional: leave it out for high
  efficiency, or in for most accurate current limit. PGOOD RUN RPG
