Overview
The Texas Instruments 5962-8768101V2A is a radiation-tolerant, QML Class V dual-output PWM controller designed for high-speed applications. It operates with a maximum input voltage of 30V and supports switching frequencies up to 1MHz. The device features current-mode control architecture and is housed in a 20-pin LCCC package. It functions within an extended temperature range from -55°C to +125°C, ensuring reliability in harsh environments.
Feature Summary
- Radiation-tolerant design qualified for QML Class V space applications
- High-speed current-mode PWM control architecture
- Dual-output capability for complex power conversion topologies
Applications
- Spacecraft power distribution systems
- Radiation-hardened DC-DC converters
- Military-grade power management modules
Procurement Notes
Verify the specific QML Class V qualification status and lot traceability requirements before procurement. Confirm that the 20-pin LCCC package dimensions match your PCB footprint exactly. Ensure environmental testing protocols align with aerospace standards. Validate supplier authorization for military-grade components to guarantee authenticity and compliance with defense supply chain regulations.
Selection Notes
Select this component when radiation hardness is mandatory for mission-critical operations. The dual-output feature suits applications requiring isolated or multi-rail generation. Current-mode control offers improved transient response compared to voltage-mode alternatives. Consider the 30V input limit and 1MHz frequency ceiling against system power density requirements.
Part Context
This part belongs to the UC1825-SP family of radiation-tolerant controllers. It serves as a specialized variant of standard PWM controllers, enhanced for space environments. The 5962 prefix indicates a military-grade specification, distinguishing it from commercial counterparts. It replaces older generations of non-radiation-hardened controllers in satellite and deep-space missions.
Replacement Considerations
Direct substitutes include other QML Class V PWM controllers such as the UC1825QFA or UC1825VEA, provided they meet the same radiation tolerance and pinout compatibility. Verify thermal performance and switching characteristics match the original design constraints.
