  High Performance Portable DC Bench Power Supply:
  Save Money and Free Up Bench Real Estate by
  Building Your Own
  Keith Szolusha The bench power supply, along with the soldering iron and
  handheld multimeter, is a required item in any electronics
  lab toolbox. Some projects require only a single, constant
  voltage supply, but more often, properly testing and
  debugging a project demands a variety of voltages and
  currents. Significant debugging time can be saved by
  using a high performance adjustable bench supply to
  dial in voltage and current at will. Unfortunately, typical
  universal adjustable bench power supplies are bulky and
  expensive—at least the better-performing versions—and
  have a number of limitations. None are truly portable
  (handheld) due to necessary heat dissipation structures.
  Furthermore, even high cost supplies do not support zero
  current or voltage, and cannot match the transient and
  short performance exhibited by the supply shown here.

  L DESIGN IDEAS Robust DC/DC Step-Down Converter
  in 3mm Г— 3mm DFN Resists 60V
  by Chuen Ming Tan
  Input Surges
  Introduction The LTC3642 comes in compact 3mm
  Г— 3mm DFN and MS8E packages with
  integrated MOSFETs, as shown in
  Figure 2. It is extremely easy to use,
  requiring no loop compensation. The
  3.3V and 5V fixed output versions only
  need two capacitors and an inductor
  for operation (see Figure 3).
  The constant peak switch current
  thresholds of these devices inherently
  protect them from output short circuits. Moreover, each of these devices
  can reduce its peak switch current
  threshold such that smaller input and
  output capacitors can be used.
  When operating with a high input
  voltage source, the LTC3642’s RUN
  pin can be optionally configured to VIN
  10V/DIV 50Вµs/DIV Figure 1. The LTC3642 continues to regulate
  the output despite a >45V spike on the input. 150ВµH VIN …
