The SXA10 series is targeted specifically at telecommunications, data networking, mobile
infrastructure, industrial and computer distributed power applications. An open frame
topology combining a custom IC, conservative component deratings and extensive
qualification ensures enhanced performance and reliability. All models have remote enable,
output voltage trim and adjustable undervoltage lockout setting. The products are
manufactured in a fully automated process utilising established and proven mechanical
construction technologies. Supplied in JEDEC standard trays, these products are optimized
for automated assembly using standard pick and place equipment and using industry
standard reflow profiles.
All specifications are valid over 27-75V input, no load to rated load and -40°C to 110°C hot spot
(output diode tab temperature), unless otherwise stated.
