Overview

The UC1825A-SP PWM controller is a radiation hardened version of the standard UC1825 family. Performance enhancements have been made to several of the circuit blocks.

  • 1 QML-V Qualified, SMD 5962-87681
  • 5962P8768105Vxx: - Radiation Hardness Assurance (RHA) up to 30-krad(Si) Total Ionizing Dose (TID) - Passes Functional and Specified PostRadiation Parametric Limits at 45 krad at LDR (10 mrad(Si)/s) per 1.5× Over Test as Defined in MIL-STD-883 Test Method 1019.9 Paragraph 3.13.3.b - Exhibits Low Dose Rate Sensitivity but Remains Within the Pre-Radiation Electrical Limits at 30-krad Total Dose Level, as Allowed by MIL-STD-883, TM1019
  • Compatible With Voltage-Mode or Current-Mode Control Methods
