The "SB" Series of DC/DC converters feature 1 to 2 Watts of isolated power combining compact size and high
efficiency. The small size of this 7 pin SIP package saves valuable board space in new product design. With
single or dual outputs, the SB series is ideal for a variety of demanding requirements such as those found in
the data-com/telecom, industrial control, computing, transportation, or office automation industries.
The size and pin out conform to internationally recognized packaging that is an industry standard. Operating
from a nominal 5, 12, 24 or 48 VDC input source, this PCB mountable, low profile miniature converter provides
single or dual unregulated, isolated outputs varying from 5 to 15VDC. It is designed to meet or exceed a
variety of safety and emissions requirements including CE (LVD), EN 55022 “Class A”, and UL 1950.
Reliability Incorporated also provides custom designed DC/DC Converters to meet customer specifications.
Reliability Incorporated is based in Houston, Texas, USA and is a leading provider of semiconductor
processing equipment and DC/DC converters. Corporate headquarters, located in Houston, TX, USA. DC/DC
converters are manufactured in Costa Rica.
