TDA4860** is a power factor correction (PFC) controller IC manufactured by **PHILIPS** (now NXP Semiconductors).

The TDA4860 is a power factor correction (PFC) controller IC manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features:

Specifications:

  • Supply Voltage (VCC): 10.8V to 27V
  • Operating Frequency: Adjustable up to 200 kHz
  • Maximum Duty Cycle: 95%
  • Start-up Current: < 100 µA
  • Quiescent Current: < 5 mA
  • Output Drive Current: ±1.5A (peak)
  • Error Amplifier Bandwidth: 3 MHz
  • Protection Features: Overvoltage, Undervoltage, Overcurrent

Descriptions:

The TDA4860 is designed for active power factor correction in switch-mode power supplies (SMPS). It operates in transition mode (boundary conduction mode, BCM), ensuring high efficiency and low harmonic distortion. The IC includes an integrated multiplier, error amplifier, and driver stage for controlling an external MOSFET.

Features:

  • High Power Factor (>0.99)
  • Low Harmonic Distortion
  • Internal Start-up Timer
  • Zero Current Detection (ZCD)
  • Soft Start Function
  • Overvoltage Protection (OVP)
  • Undervoltage Lockout (UVLO)
  • Adjustable Output Voltage Regulation

The TDA4860 is commonly used in AC-DC converters, LED drivers, and industrial power supplies requiring compliance with power quality standards.
