UCC2800QDREP

Power Supply Controllers, Monitors Overview

The UCC2800QDREP is a military-enhanced, low-power, BiCMOS current-mode PWM controller manufactured by Texas Instruments. It operates within a supply voltage range of 3.5 V to 18 V and supports switching frequencies up to 1 MHz. The device features a maximum duty cycle of 100% and provides an output drive current of 1 A. It functions reliably across an extended temperature range from -55°C to +125°C. Packaged in an SOIC-8 surface-mount format, it includes internal compensation and protection features suitable for high-reliability applications.

Power Supply Controllers, Monitors Feature Summary

• Supports 100% maximum duty cycle operation for specific converter topologies
• Integrated internal compensation reduces external component count
• Military-grade reliability with enhanced burn-in screening
• Current-mode control architecture for improved transient response

Power Supply Controllers, Monitors Applications

• High-reliability aerospace power supplies
• Military-grade isolated DC/DC converters
• Aviation flyback and forward converter designs
• Harsh environment industrial power systems

Power Supply Controllers, Monitors Procurement Notes

Verify the complete ordering part number including suffixes to ensure correct military qualification level and package variant. Confirm RoHS compliance status as required by project specifications. Validate that the supplier provides traceable documentation consistent with defense industry standards. Check for any specific handling requirements related to the SOIC-8 package during assembly processes.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing for extreme temperature environments requiring -55°C to +125°C operation. Choose the UCC2800QDREP over commercial variants if military screening and burn-in are mandatory. Consider the 100% duty cycle capability when selecting between similar family members like the UCC2803 or UCC2804 which may have lower limits. Ensure the 1 MHz frequency range aligns with magnetic component design constraints.

Power Supply Controllers, Monitors Part Context

This device belongs to the UCC2800 series of current-mode PWM controllers designed for robust performance. It shares architectural similarities with the UCC2801 and UCC2802 but distinguishes itself through military-grade processing. The QDREP suffix indicates a qualified, reel-packaged version of the SOIC-8 device. It serves as a specialized alternative to standard commercial controllers in critical infrastructure applications.

Power Supply Controllers, Monitors Replacement Considerations

The UCC2800QDR is the non-qualified commercial equivalent. The UCC2800QD is the tube-packaged variant of the same military grade device. Verify pin compatibility and thermal characteristics when substituting with these alternatives.
