  Limits
  Design Note 434
  Tick Houk
  In addition to high accuracy, the LTC3811’s low minimum on-time (typically 65ns) allows users to convert a
  12V input to a 1V output at switching frequencies up to
  750kHz, optimizing load transient response and reducing
  the solution size. Introduction
  Speed and accuracy don’t always go hand-in-hand
  in DC/DC converter systems—that is, until now. The
  LTC3811 is a dual output, п¬Ѓxed frequency current mode
  DC/DC switching regulator controller designed for one of
  today’s most demanding power supply applications: high
  current, low voltage processor core supplies. A Dual Output, 2-Phase Supply with Differential
  Remote Sensing and Inductor DCR Sensing
  Figure 1 illustrates a dual output supply using the LTC3811.
  The 1.5V, 15A output is regulated using the integrated
  differential remote sense amplifier and tracks the output of
  channel 1 during start-up. Both outputs use DCR sensing
  in order to maximize efficiency and operate 180° out of With supply current requirements in excess of 100A
  and supply voltages as low as 1V, every milliohm of
  PCB resistance and every millivolt of IR drop count. The
  LTC3811 has an output voltage tolerance of В±0.5% over …
