UCC28510DW

Overview

The UCC28510DW is an advanced Power Factor Correction (PFC) and Pulse Width Modulation (PWM) combination controller manufactured by Texas Instruments. Designed for offline power systems, it integrates average current mode control with enable functionality and overvoltage protection (OVP). The device operates within a switching frequency range up to 500 kHz and supports Continuous Conduction Mode (CCM). It features UVLO thresholds for on/off control and is housed in a SOIC-16 package suitable for surface mount installation.

Feature Summary

• Integrates PFC and PWM control functions into a single component for complete offline power system management
• Utilizes average current mode control architecture for enhanced performance
• Includes built-in overvoltage protection and enable capabilities
• Supports continuous conduction mode operation

Applications

• Offline power supply systems requiring combined PFC and PWM control
• Power factor correction stages in AC-DC converters
• Systems utilizing average current mode control strategies

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and functional variations. Ensure compatibility with required operating temperatures and voltage levels. Confirm RoHS compliance status through manufacturer datasheets. Validate package dimensions against PCB footprint requirements prior to procurement.

Selection Notes

Select this component for applications demanding integrated PFC and PWM control in a single IC. Consider the 500 kHz maximum switching frequency and CCM support when designing magnetic components. Evaluate the SOIC-16 package constraints for thermal management and board space. Verify that the UVLO thresholds meet system startup and shutdown requirements.

Part Context

The UCC28510 series belongs to Texas Instruments' portfolio of advanced combination controllers. These devices are engineered to simplify the design of high-performance offline power supplies by reducing component count. The DW variant specifically denotes the SOIC-16 surface-mount package configuration.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify electrical parameters and pin compatibility before replacing.
