TDA4863 is a power factor correction (PFC) controller IC manufactured by **Infineon Technologies**.

The TDA4863 is a power factor correction (PFC) controller IC manufactured by Infineon Technologies.

Specifications:

  • Input Voltage Range: 85 V to 265 V (AC)
  • Output Voltage: Typically 400 V (DC)
  • Switching Frequency: Adjustable (typically around 100 kHz)
  • Operating Temperature Range: -40°C to +125°C
  • Package: P-DSO-8 (PowerSO-8)
  • Control Method: Transition Mode (TM) PFC for high efficiency
  • Supply Voltage (VCC): Up to 30 V
  • Current Sense Input: Integrated for accurate current regulation

Descriptions:

The TDA4863 is designed for active power factor correction in switch-mode power supplies (SMPS). It operates in transition mode (boundary conduction mode) to optimize efficiency while minimizing switching losses. The IC includes features for soft-start, overvoltage protection (OVP), and undervoltage lockout (UVLO).

Features:

  • High Power Factor (>0.99)
  • Low THD (Total Harmonic Distortion)
  • Integrated Startup Timer
  • Zero Current Detection (ZCD) for transition mode operation
  • Overvoltage Protection (OVP)
  • Undervoltage Lockout (UVLO)
  • Adjustable Output Voltage
  • Low Standby Power Consumption

This IC is commonly used in LED drivers, AC-DC adapters, and industrial power supplies requiring high efficiency and compliance with power quality standards.
