1 / 2 page 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 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.
