UCC28084PWG4

DC DC Switching Controllers Overview

The UCC28084PWG4 is a current-mode push-pull PWM controller designed for half-bridge and push-pull topologies. It features programmable slope compensation and operates within a supply voltage range of 4.1V to 15V. The device supports switching frequencies up to 1MHz with a maximum duty cycle of 50%. It provides two output channels capable of sourcing 1A each, housed in an 8-TSSOP package. Operating temperatures span from -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Current-mode control architecture with programmable slope compensation
• Supports half-bridge and push-pull converter topologies
• Integrated transistor drivers for high-current output stages

DC DC Switching Controllers Applications

• High-frequency DC-DC converters
• Half-bridge power supplies
• Push-pull transformer-coupled applications

DC DC Switching Controllers Procurement Notes

This component has reached End-of-Life status and is no longer manufactured by Texas Instruments. Verification of availability should focus on remaining distributor stock or authorized aftermarket sources. Designers must confirm the specific revision and authenticity of any available units prior to integration into production systems.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring current-mode operation with push-pull or half-bridge configurations. Ensure the application frequency aligns with the device's 1MHz capability. Verify that the load requirements fit within the specified output current limits and that the operating temperature range meets the environmental conditions of the target system.

DC DC Switching Controllers Part Context

The UCC28084 belongs to the UCC2808x family of current-mode PWM controllers. This series is engineered for efficient power conversion in isolated and non-isolated applications. The PWG4 suffix indicates a specific tape-and-reel packaging variant within the TSSOP-8 form factor, distinct from tube-packaged equivalents like the UCC28084PWR.

DC DC Switching Controllers Replacement Considerations

The UCC28084PWR is listed as a manufacturer-recommended alternative. However, it shares the same End-of-Life status. No other active substitute part numbers are confirmed in the provided documentation.
