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
expensiveвЂ”at least the better-performing versionsвЂ”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.

LвЂ‰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 LTC3642вЂ™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 …
