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.

Valid for 48V input, nominal load and 25˚C operation.
For applications with input voltages between 36 and 75V, and operating
ambient temperatures of -10˚C to +70˚C the device will deliver an extra
10% output power. The device will continue to meet all specifications
listed in this data sheet. See output characteristic diagram below.
Demonstrated life test to-date is 1,300,000 hours at 36˚C. This figure
includes a calculated acceleration factor of 2.14, based on an activation
energy of 0.55eV.
To order an Evaluation Kit which contains a SXA10 model pre-mounted
on a circuit card with test points for easy testing in the laboratory, please
add the suffix ‘-EVAL’ to the model number, e.g. SXA10-48S05-EVAL.
Please see the SXA10 Evaluation Board User Guide for further details.
