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 …
