V62/03624-04XE

Overview

The V62/03624-04XE is a military-enhanced, low-power BiCMOS current-mode PWM controller manufactured by Texas Instruments. It operates with a switching frequency of 1 MHz and supports a maximum duty cycle of 100%. The device provides an output current capability of 1 A and functions within a temperature range from -55°C to +125°C. Housed in an SOIC-8 surface-mount package, it features rise and fall times of 41 ns and 44 ns respectively. This component belongs to the UCC2803 series and serves as a radiation-tolerant solution for demanding power conversion applications.

Feature Summary

• Military-grade reliability with enhanced performance specifications
• Current-mode PWM control architecture for precise regulation
• Wide operating temperature range suitable for harsh environments

Applications

• Aerospace power systems
• Military communication equipment
• Radiation-hardened power supplies

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm exact electrical tolerances and qualification status. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm availability through authorized distributors only to prevent counterfeit components. Check for any recent product change notifications that may affect pinout or functionality.

Selection Notes

Select this component when high reliability and radiation tolerance are required in space-constrained designs. The 1 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the SOIC-8 package for ease of assembly in automated manufacturing processes. Evaluate thermal dissipation needs given the 125°C maximum operating temperature limit.

Part Context

This part is a military-enhanced variant within the UCC2803 family of current-mode PWM controllers. It shares functional similarities with commercial counterparts but undergoes stricter screening and testing protocols. The V62 prefix indicates a specific procurement code often associated with government or defense contracts requiring verified supply chain integrity.

Replacement Considerations

V62/03624-01XE is listed as an alias for this component family.
