UCC28084DR

DC DC Switching Controllers Overview

The UCC28084DR is a current-mode push-pull switching controller manufactured by Texas Instruments, designed for high-frequency power conversion applications. It operates within a supply voltage range of 4.1V to 15V and supports half-bridge and push-pull topologies. The device features a maximum switching frequency of 1 MHz and a maximum duty cycle of 50%. It provides two outputs with a drive capability of 1 A at 4.3 V. The component is housed in an SOIC-8 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Supports current-mode control with programmable slope compensation for stable operation under varying load conditions.
• Capable of driving transformer-based topologies including half-bridge and push-pull configurations.
• Integrates internal circuitry for precise switching frequency management up to 1 MHz.

DC DC Switching Controllers Applications

• High-efficiency DC-DC converters utilizing push-pull topology
• Half-bridge power supply designs requiring current-mode control
• Industrial power systems operating within specified thermal limits

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DR' confirms the SOIC-8 surface-mount package variant. Confirm RoHS compliance status as indicated in official documentation. Ensure design compatibility with the 4.1V to 15V supply voltage range. Validate that the 1 MHz switching frequency aligns with system requirements. Check for any obsolescence notices or lifecycle changes from the manufacturer.

DC DC Switching Controllers Selection Notes

Select this component when a push-pull or half-bridge topology is required with current-mode control. Ensure the application demands a switching frequency up to 1 MHz. Verify that the SOIC-8 package fits the PCB layout constraints. Confirm the operating temperature range meets environmental specifications. Consider the 1 A output drive capability for gate driver requirements.

DC DC Switching Controllers Part Context

This part belongs to the UCC2808x series of switching controllers from Texas Instruments. These devices are engineered for isolated power conversion applications. The series emphasizes performance in high-frequency environments. The DR suffix specifically denotes the tape-and-reel packaging format for automated assembly.

DC DC Switching Controllers Replacement Considerations

The UCC28084DRG4 is a documented equivalent variant within the same product family. Verify pinout and electrical specifications match before substitution. Confirm package dimensions remain compatible with existing footprints.
