UCC2805QDREP

Overview

The UCC2805QDREP is a military-enhanced, low-power BiCMOS current-mode PWM controller from Texas Instruments. It operates with a switching frequency of 1 MHz and supports a maximum duty cycle of 50%. The device provides a single output with a drive current capability of 1 A. It functions within an extended temperature range from -40°C to +125°C. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Military-grade enhancement for reliability
• BiCMOS technology for low power consumption
• Current-mode PWM control architecture

Applications

• Military power supply systems
• Aviation electronic equipment
• Ruggedized industrial power converters

Procurement Notes

Verify the specific suffix 'QDREP' against official Texas Instruments documentation to confirm military qualification status and RoHS compliance details. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements. Cross-reference the datasheet revision history to validate the operating temperature range and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when designing power supplies requiring military-grade reliability and low power consumption. The 1 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. The 50% maximum duty cycle limits its suitability for certain topologies; verify circuit requirements against this constraint during the design phase.

Part Context

This part belongs to the UCC2805 series of current-mode PWM controllers. It shares architectural similarities with commercial variants but includes enhancements for harsh environments. The SOIC-8 package is standard for this family, facilitating integration into compact designs while maintaining thermal performance within the specified industrial and military temperature ranges.
