  42V Quad Monolithic Synchronous Step-Down Regulator
  with 30ВµA Quiescent Current
  Design Note 544
  Zhongming Ye
  Introduction
  Industrial and automotive applications require robust,
  easy-to-use, compact DC/DC converters to produce
  a variety of low voltage power supplies. The LT8602
  monolithic quad synchronous step-down converter in
  a 6mm Г— 6mm package is capable of providing four
  outputs from a wide input range of 3V to 42V. It is
  versatile and easy to use with features such as low
  EMI and adjustable operating frequency up to 2.2MHz.
  It consumes only 30ВµA quiescent current from the
  input source even when regulating the outputs.
  Small Size, Low EMI, Quad Step-Down
  Solution
  The LTВ®8602 integrates two high voltage (HV) and
  two low voltage (LV) synchronous regulators in a
  QFN (6mm Г— 6mm) package. Replacing external
  Schottky diodes with internal synchronous switches
  minimizes the solution size and also increases efficiency, reducing power dissipation. Figure 1. Top Center View of
  the Demo Board DC1949A …
