MSK 5044RH RAD Hard 3.5A Switching Regulator Total Dose Radiation Test Report
■The total dose radiation test plan for the MSK 5044RH was developed to qualify the devices as RAD Hard to 100 KRADS(Si). The testing was performed beyond 100 KRADS(Si) to show trends in device performance as a function of total dose. The test does not classify maximum radiation tolerance of the device, but simply offers designers insight to the critical parameter-shifts up to the specified total dose level.
■MIL-STD-883 Method 1019.7 and ASTM F1892-06 were used as guidelines in the development and implementation of the total dose test plan for the MSK 5044RH.
●Summary
■Based on the test data recorded during radiation testing and statistical analysis, the MSK5044RH qualified as a 100 Krad(Si) radiation hardened device. Switching Frequency and Current Limit exhibited the most significant shift due to irradiation. At 100Krad(Si), Switching Frequency decreased 5.5% while Current Limit increased 17%. All performance curves stayed within the post irradiation requirements up to 150Krad(Si).
