SC5A SERIES
HDLV
Family
Description
The SC5A is a 5-amp, full-featured, non-isolated DC-DC converter.
Designed for 12 V distributed power systems, the SC5A comes in a SIP
form factor to minimize board space and maximize power density. It
combines an industry-standard pin-out with a mounted height of only
0.5 inches. Using Bourns Switch Power's proprietary V
2TM
architecture with a
12 V input, the SC5A provides ultrafast transient response, improved line and
load regulation, and very high efficiency.
