  60V Low IQ, Dual Output Synchronous Step-Down Controller
  with Adjustable Gate Drive
  Design Note 562
  Victor Khasiev
  Introduction
  The LTC В®3892 is a dual output synchronous buck
  controller featuring a wide input voltage range of
  4.5V to 60V and an output voltage of 0.8V to 99%
  of VIN. The combination of the LTC3892’s built-in
  FET drivers and external FETs yield high efficiency
  and high power capability, up to 97% efficiency and
  over 60A output current 2. Its robust design—an IC
  operating junction temperature range of –55°C to
  150°C—meets the needs of industrial, automotive,
  telecom, military, aerospace and distributed systems. and 3.9ВµA shutdown current, maintaining battery
  charge as long as possible. The LTC3892’s wide
  input voltage range satisfies the demanding requirements of industrial and automotive applications,
  which are distinguished by their lack of stable, high
  quality voltage sources. For example, in automotive
  environments, a 12V nominal voltage rail can range
  from a low 5V to above 50V during cold starts and
  load dumps. The LTC3892’s ability to sustain the
  output in the face of high voltage inputs eliminates …
