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 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.
