HDLV SC15A DAC Family Description The SC15A DAC is a low-cost, 15-amp, nonisolated DC-DC converter with an amazingly small footprint of only 0.8 in2. Designed for today's high power microprocessors, the SC15A accepts either 5V or 3.3V inputs and offers DAC controlled outputs from 1.25V to 3.5V. Using Switch Power's proprietary V2TM architecture, the SC15A DAC 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.
