  DESIGN IDEAS L High Voltage Step-Down Controller
  Delivers High Power with Minimum
  Number of Components
  by Stephanie Dai and Theo Phillips Introduction
  The LTC3824 is a non-synchronous
  buck controller that accepts inputs
  from 4V to 60V and is robust in the
  presence of large input transient
  voltages (FigureВ 1). It draws just
  40ВµA of quiescent current in Burst
  Mode operation, prolonging run time
  in battery-powered applications. To
  handle the wide range of temperatures
  found in automotive and industrial
  applications, the LTC3824 comes in
  a thermally enhanced 10-pin MSE
  package. 12V/2A from a
  Wide Input Voltage Range A typical LTC3824 application (FigureВ 2) can deliver up to 2A of
  continuous load current, and provides
  up to 90% efficiency at 1A (FigureВ 3).
  Sturdy 2A, 8V gate drivers accommodate industrial high voltage P-channel
  MOSFETs. By using a P-FET as a main
  switch, the controller is able to operate …
