V62/03624-01XE

Overview

V62/03624-01XE is a military-enhanced switching controller from Texas Instruments, based on the UCC2800 architecture. It utilizes BiCMOS technology and operates with current-mode PWM control. The device supports a maximum switching frequency of 1 MHz and delivers an output drive current of 1 A. It features a maximum duty cycle of 100%, with rise and fall times of 41 ns and 44 ns respectively. Operating within a temperature range of -55°C to +125°C, it is housed in an SOIC-8 surface-mount package.

Feature Summary

• Implements current-mode pulse-width modulation for precise power regulation
• Utilizes BiCMOS process technology for enhanced performance
• Supports up to 100 percent continuous duty cycle operation

Applications

• Military-grade power supply systems
• Aviation electronic equipment
• Ruggedized industrial control units

Procurement Notes

Verify the complete part number including the V62 prefix to ensure correct military qualification status. Confirm that the specific suffix matches the required tape-and-reel packaging configuration. Cross-reference the manufacturer datasheet for the base UCC2800 specifications to validate electrical parameters against system requirements before integration.

Selection Notes

Select this component when high reliability and extended temperature tolerance are mandatory. The 1 MHz switching frequency allows for compact passive component sizing. Ensure the application requires current-mode control topology and can accommodate the SOIC-8 thermal characteristics. Verify input voltage ranges align with the specific converter design constraints.

Part Context

This part belongs to Texas Instruments' V62 qualified product line, indicating screening and testing beyond standard commercial specifications. It serves as a military-grade variant of the UCC2800 series, designed for environments requiring strict adherence to defense industry standards and long-term operational stability.

Replacement Considerations

The base model UCC2800QDREP shares identical functional specifications but may lack the specific V62 military screening documentation. Verify that any substitute meets the exact temperature range and radiation hardness requirements if applicable.
