  L DESIGN FEATURES Compact No RSENSE Controllers
  Feature Fast Transient Response
  and Regulate to Low VOUT
  from Wide Ranging VIN
  by Terry J. Groom
  Introduction
  The trend in digital electronics is to
  lower voltages and increasing load currents. This puts pressure on DC/DC
  converters to produce low voltages
  from increasingly voltage-variable
  supplies, such as stacked batteries
  and unregulated intermediate power
  buses, so power converters must be
  optimized for low output voltages, low
  duty factors, and wide control bandwidths. To meet these requirements,
  the DC/DC controller IC must offer
  high voltage accuracy, good line and
  load regulation, and fast transient
  response. The constant on-time valley current mode architecture used in
  the LTC3878 and LTC3879 is ideally
  suited to low duty factor operation,
  offering a compact solution with excellent system performance.
  The LTC3878 and LTC3879 are …
