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^2TMarchitecture, 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.
