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 V2TM 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.
