  L DESIGN FEATURES Industrial/Automotive Step-Down
  Regulator Accepts 3.6V to 36V
  and Includes Power-On Reset and
  Watchdog Timer in 3mm Г— 3mm QFN
  by Ramanjot Singh Introduction
  As the number of microprocessors in
  automotive and industrial applications continues to expand, so does the
  need for rugged step-down regulators
  that can operate over a wide input
  voltage range and withstand high
  voltage transients and output shorts.
  Microprocessor-based applications
  also require supervisory functions,
  such as power-on reset (POR) and
  watchdog timing, to ensure high system reliability. The regulator must
  have high efficiency at light loads
  to increase battery life. The LT3689
  delivers all of these features in tiny
  16-pin 3mm Г— 3mm QFN and 16-pin
  MSOP packages. Features of the LT3689
  Step-Down Regulator The LT3689 employs a constant frequency, current mode architecture to
  provide 800mA of continuous output
  current. The part operates from a …
