TDA4863GXUMA2

Overview

The TDA4863GXUMA2 is a Power Factor Correction (PFC) Boost Controller IC from Infineon Technologies, designed for high power factor and low total harmonic distortion applications. It operates within a supply voltage range of -0.3 V to +22 V and supports an operating temperature range from -40 °C to +150 °C. The component is housed in an SOIC-8 surface-mount package with dimensions of 5 mm x 4 mm x 1.5 mm. Key electrical characteristics include a start-up supply current of 100 µA, a maximum source current of -6 mA, a maximum reverse current of 30 mA, and a maximum supply current of 20 mA.

Feature Summary

• Controls boost converter as an active harmonics filter
• Internal start-up with low current consumption
• Zero current detector for discontinuous operation mode
• High current totem pole gate driver

Applications

• Power factor correction circuits
• Active harmonic filters
• High power factor power supplies

Procurement Notes

Verify the specific suffix GXUMA2 against official Infineon documentation to confirm the tape-and-reel packaging format and moisture sensitivity level. Confirm end-of-life status and availability through authorized distributors, as discontinuation notifications may affect long-term sourcing. Ensure compatibility with existing board layouts due to the SOIC-8 pin configuration.

Selection Notes

Select this controller for designs requiring high efficiency and compliance with harmonic emission standards. The integrated zero-current detection supports discontinuous conduction mode operation, which can reduce switching losses. The wide operating temperature range makes it suitable for industrial environments. Verify that the internal reference trim accuracy meets the system's regulation requirements.

Part Context

This component belongs to the TDA4863 series of PFC controllers. It is part of Infineon's portfolio for power management integrated circuits. The device is specifically engineered to improve power quality in AC-DC conversion systems by shaping the input current to follow the input voltage waveform closely.

Replacement Considerations

Check for direct pin-compatible alternatives within the TDA486x family or newer generations from Infineon. Verify functional equivalence regarding control loop dynamics and gate drive capabilities before substitution.
