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.
SPECIFICATION
All specifications are valid over 27-75V input, no load to rated load and -40C to 110C hot spot
(output diode tab temperature), unless otherwise stated.
