UCC28084DRG4

DC DC Switching Controllers Overview

The UCC28084DRG4 is a current mode push-pull PWM controller manufactured by Texas Instruments, designed for high-performance power conversion applications. It operates within a supply voltage range of 4.1V to 15V and supports switching frequencies up to 200kHz. The device features a maximum duty cycle of 49% and includes programmable slope compensation to ensure stability. It provides two output channels with a drive capability of 1A, housed in an 8-SOIC package suitable for surface mount installation.

DC DC Switching Controllers Feature Summary

• Implements current mode control architecture with integrated programmable slope compensation for enhanced stability.
• Supports half-bridge and push-pull topologies with dual output drivers capable of sourcing 1A.
• Includes built-in soft-start functionality and under-voltage lockout protection mechanisms.

DC DC Switching Controllers Applications

• High-efficiency DC-DC converter designs
• Industrial power supply systems
• Telecommunications equipment power stages

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distributors as the part status may be discontinued or limited. Confirm package integrity and pin alignment against the 8-SOIC specification. Ensure environmental compliance documentation matches RoHS3 requirements. Cross-reference datasheet revisions to confirm electrical characteristics align with design specifications before final procurement.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring precise current mode regulation in push-pull configurations. Evaluate thermal performance within the -40°C to 85°C operating range. Consider the 200kHz frequency limit when designing magnetic components. Verify that the 49% duty cycle constraint meets the specific transformer turns ratio requirements for the target voltage conversion ratio.

DC DC Switching Controllers Part Context

This component belongs to the UCC2808x series of current mode controllers from Texas Instruments. It shares functional similarities with the UCC28084DR but differs in packaging and lifecycle status. The DRG4 suffix indicates a specific tape-and-reel packaging variant compliant with certain manufacturing standards, distinct from tube-packaged alternatives like the UCC28084PWG4.

DC DC Switching Controllers Replacement Considerations

The UCC28084DR is a confirmed substitute part number offering identical electrical specifications. Verify that the alternative package type matches the PCB footprint constraints. Ensure that any pin-compatible replacements maintain the same UVLO thresholds and drive current capabilities to prevent circuit malfunction.
