UCC2802QDREP

Overview

The UCC2802QDREP 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 up to 100% maximum duty cycle. The device provides a peak output drive current of 1 A and functions within an operating temperature range from -40°C to +125°C. It is housed in an SOIC-8 surface-mount package.

Feature Summary

• Military-grade enhancement for extended reliability
• Low-power BiCMOS technology implementation
• Current-mode PWM control architecture

Applications

• High-reliability power supply systems
• Military aerospace electronic equipment
• Industrial power conversion units

Procurement Notes

Verify the specific suffix 'REP' indicates the required military qualification level. Confirm the SOIC-8 package dimensions match the design constraints. Ensure the 1 MHz switching frequency aligns with the target application requirements. Check for RoHS compliance details if environmental regulations apply.

Selection Notes

Select this component when military-grade reliability is mandatory alongside low-power operation. The 1 A output drive capability suits moderate load applications. Consider the 1 MHz frequency for compact magnetic component sizing. Verify thermal management needs for the specified temperature range.

Part Context
