General Information

The SC15A DAC is a low-cost, 15 amp,

non-isolated DC-DC converter with an

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.

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.
