5962-9451301MPA

Overview

The Texas Instruments 5962-9451301MPA is a military-grade, low-power BiCMOS current-mode PWM controller. It operates within a switching frequency of 1 MHz and supports an output current of 1 A. The device accommodates Boost, Flyback, and Forward topologies. It features UVLO thresholds at 9.4 V (on) and 7.4 V (off). Operating temperature ranges from -55°C to +125°C. The component is housed in an 8-pin CDIP package.

Feature Summary

• Integrates error amplifier with leading edge blanking for stable operation
• Includes soft start functionality to limit inrush current
• Utilizes BiCMOS technology for low power consumption

Applications

• Military DC-DC converter systems
• High-reliability power supply designs
• Aviation electronic equipment

Procurement Notes

Verify the specific suffix 'MPA' confirms the military grade qualification and CDIP-8 package type. Confirm RoHS status as this variant may not be compliant. Ensure the source document explicitly lists this part number to avoid substitution errors with commercial equivalents.

Selection Notes

Select this component when military reliability standards are mandatory. The 1 MHz frequency allows for compact passive components. Verify that the 1 A output current meets system requirements. Check compatibility with the required input voltage range against the UVLO thresholds.

Part Context

This part belongs to the UC1856 family of switching controllers. It is designed for high-performance applications requiring precise current-mode control. The military specification ensures operation under extreme environmental conditions compared to standard industrial variants.
