Overview
The Texas Instruments 5962-8768105VEA is a radiation-tolerant, high-speed Pulse Width Modulation (PWM) controller designed for military and aerospace applications. It features QML-V qualification and supports dual-output configurations with a 30-V input range. The device operates at a switching frequency of 1 MHz and provides a 2-A drive capability. Packaged in a 16-pin CDIP format, it functions as a positive output step-up, step-up/step-down DC-DC controller IC suitable for harsh environments.
Feature Summary
- QML-V qualified for Class V reliability standards
- Radiation tolerant up to 30 kRad (Si) total ionizing dose
- High-speed PWM control optimized for demanding power conversion tasks
Applications
- Military power supply systems
- Aerospace electronic equipment
- Harsh environment DC-DC converters
Procurement Notes
Verify the specific revision level and manufacturing lot traceability upon order confirmation. As a QML-V qualified component, ensure that the procurement channel provides appropriate certification documentation. Confirm package integrity and lead times due to potential limited availability or special order requirements associated with this military-grade part number.
Selection Notes
Select this component when radiation tolerance and high-speed PWM control are required in a through-hole package. It serves as a robust solution for dual-output topologies where input voltages reach 30 V. Ensure the application design accommodates the 1 MHz switching frequency and the thermal characteristics of the CDIP-16 package for optimal performance.
Part Context
This part belongs to the SN54 series of logic and control devices from Texas Instruments, specifically tailored for military specifications. The 5962 prefix indicates a direct buy or military-grade variant. It complements other radiation-hardened controllers by offering high-frequency operation and dual-output capabilities within a standardized ceramic DIP footprint.
Replacement Considerations
Direct substitutes include other QML-V qualified PWM controllers from Texas Instruments such as the UC1825 series variants. Verify pin compatibility and radiation tolerance levels before substitution. Non-QML equivalents may lack the necessary environmental ruggedness for certified military applications.
