SC10A SERIES
HDLV
Family
Description
The SC10A is a low-cost, 10-amp, non-isolated DC-DC converter. The SIP
form factor and high power density combine to minimize the board area
required for power. It uses an industry-standard pin-out and Bourns
Switch Power's proprietary V2TM architecture. The SC10A provides ultrafast
transient response, improved line and load regulation, and very high
efficiency.
