Designed for today’s high power microprocessors, the SC15A accepts either 5 V or 3.3 V inputs and offers DAC controlled outputs from 1.25 V to 3.5 V. Using Bourns proprietary V2™ 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.
