SC10A DAC Series – Power Module
Standard Options
General Information
The SC10A DAC is a low-cost, 10 amp,
non-isolated DC-DC converter with an
amazingly small footprint. Designed for
today’s high power microprocessors, the
SC15A accepts a 5 V input and a DAC
controlled output from 1.25 V to 3.5 V.

Using Bourns proprietary V2™
architecture, the SC10A 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.
