Overview
The TDA4863-2 is a power-factor controller (PFC) IC designed for high power factor and low total harmonic distortion (THD). It operates as a boost controller within the DC to DC conversion category. The device supports a maximum operating supply voltage of 22 V and functions across an extended temperature range from -40 °C to +150 °C. It is available in surface-mount SOIC packages, specifically the TDA4863-2G variant.
Feature Summary
- Integrated control architecture optimized for high power factor correction
- Designed to achieve low total harmonic distortion in power supplies
- Capable of operation at elevated junction temperatures up to 150 °C
Applications
- High power factor AC-DC power supplies
- Low THD power management systems
- Boost converter topologies requiring PFC integration
Procurement Notes
Verify component authenticity through authorized Infineon channels or certified distributors. Confirm package type and revision history against official datasheets. Check for end-of-life status or discontinuation notices prior to procurement planning. Ensure environmental compliance documentation matches project requirements.
Selection Notes
Select this component for applications requiring integrated PFC functionality with high thermal tolerance. Consider the SOIC package format for surface-mount assembly needs. Evaluate the 22 V supply limit against system input specifications. Verify compatibility with external boost components for the intended power level.
Part Context
The TDA4863-2 belongs to Infineon's family of power-factor correction controllers. It serves as a specialized solution for improving efficiency in switching power supplies. The device integrates control logic to manage boost converter operation, distinguishing it from general-purpose PWM controllers by its focus on power quality metrics.
Replacement Considerations
TDA4863GXUMA2 and TDA4863GNT are listed as related Power Factor Correction Controllers. Verify pinout and electrical characteristics before substitution.
