Preliminary Data
SB Series of DC/DC Converters
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 datacom/telecom, industrial control, com-
puting, transportation, or office automation industries.
Reliability Incorporated also provides custom designed
DC/DC Converters to meet customer specifications, and
welcomes the opportunity to design and manufacture
more such solutions.
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 meets or exceeds a
variety of safety and emissions requirements including
CE (LVD), EN 55022 “Class A”, and UL 1950.
Reliability Incorporated is based in Houston,
Texas, USA and is a leading provider of semiconductor
processing equipment and DC-to-DC power converters.
The DC-to-DC converters are manufactured by and sold
through RICR de Costa Rica, S.A., which is a wholly
owned subsidiary of Reliability Incorporated. The
Houston facility is ISO 9001 certified and the facilities in
San Jose, Costa Rica and Singapore are both ISO 9002
certified.
