HDLV SC15A SERIES Family Description The SC15A is a low-cost, 15-amp, non-isolated DC-DC converter with an amazingly small footprint of only 0.8 in2. Designed for today's high power microprocessors, the SC15A accepts either 5 V or 3.3 V inputs and offers outputs from 1.3 V to 3.3 V. The SC15A 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 SC15A 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.
