UC1825A-SP
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
- Practical Operation at Switching Frequencies to 1 MHz
- 50-ns Propagation Delay to Output
- High-Current Dual Totem Pole Outputs (2-A Peak)
- Trimmed Oscillator Discharge Current
- Low 100-μA Start-Up Current
- Pulse-by-Pulse Current Limiting Comparator
- Latched Overcurrent Comparator With Full Cycle Restart
