SC20A Datasheet, PDF (1/2 Pages) Bourns Electronic Solutions – low-cost, 20-Amp, non-isolated DC-DC converter

SC20A SERIES
HDLV
Family
Description
The SC20A is a low-cost, 20-Amp, non-isolated DC-DC converter with
an amazingly small footprint of only 0.8 in². Designed for today's high
power microprocessors, the SC20A accepts either 5 V or 3.3 V inputs and
offers outputs from 1.3 V to 3.3 V. The SC20A also uses an industry-
standard pin-out making it easy to increase power in existing designs.
Using Bourns Switch Power's proprietary V^2TM architecture, the SC20A
provides ultrafast transient response, improved line and load regulation, and
very high efficiency. It also incorporates short-circuit protection, Enable / Disable
control, output voltage trim, and remote sense.
