5962-8670404XA

Overview

The Texas Instruments 5962-8670404XA is a military-grade current mode PWM controller housed in a 20-LCCC package. It operates within a temperature range of -55°C to 125°C and functions as a power supply controller based on the UC1845 architecture.

Feature Summary

• Implements current mode pulse width modulation control for switching power supplies
• Designed for military specifications with extended industrial temperature tolerance
• Utilizes a 20-lead ceramic leaded chip carrier package for rugged environments

Applications

• Military power supply systems
• High-reliability DC-DC converters
• Aviation electronic equipment power management

Procurement Notes

Verify the specific revision suffix and manufacturing date code against the latest official datasheet to ensure compliance with current military standards. Confirm that the 20-LCCC package matches the target board footprint and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when designing power systems requiring strict adherence to military environmental standards and high reliability. Ensure the application utilizes current mode control topology and can accommodate the specific pinout and thermal characteristics of the LCCC package.

Part Context

This part belongs to the family of high-reliability power management integrated circuits manufactured by Texas Instruments. It serves as a radiation-hardened or space-qualified alternative to commercial grade controllers, ensuring stable operation in harsh electromagnetic and thermal conditions typical of defense applications.

Replacement Considerations

Direct cross-reference requires matching the UC1845 functional core and 20-LCCC package. Verify pin compatibility and electrical parameters against the original design specifications before substituting with other military-grade PWM controllers.
