A family of high-reliability power management ICs from Texas Instruments target applications exposed to long-term radiation and extreme temperatures, such as downhole drilling, x-ray imaging, satellite systems and high-altitude avionics. The UC18xx PWM controller and the UC1525B-SP allow greater than 30 krad(Si) tolerance to low-dose rate radiation. In addition, three parts in the SN54ACxx AC logic family reach a total irradiated dose level of 50 krad(Si) to allow for lower leakage current and improved radiation performance. An ELDRS radiation test summary is available upon request.
