LSO SERIES

28V Input, Single/Dual Output

Design Methodology

The LSO Series was developed using a proven

conservative design methodology derived from other

space level designs that includes selection of

established reliability components and fully derating

to the requirements of MIL-STD-1547, MIL-PRF-975

and NASA EEE-INST-002 except for the CDR type

ceramic capacitors, a capacitor with 50V rating is

used for in-circuit voltage stress of less than 10V. A

magnetic feedback circuit is utilized instead of opto

-couplers to minimize temperature, aging and

radiation sensitivity. PSPICE was used extensively

to predict and optimize circuit performance for both

beginning and end-of-life. Thorough design

analyses include stress, thermal, and reliability

(MTBF).
