SC15A DAC Series – Power Module
General Information
The SC15A DAC 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 DAC
controlled outputs from 1.25 V to 3.5 V.
Using Bourns proprietary V²â„¢ 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.
