UC3854DW is a high-performance power factor correction (PFC) controller manufactured by UNITRODE.

The UC3854DW is a high-performance power factor correction (PFC) controller manufactured by UNITRODE. Below are its key specifications, descriptions, and features:

Specifications:

  • Input Voltage Range: 10V to 17V (operating)
  • Output Current: 1.5A (peak gate drive)
  • Switching Frequency: Adjustable up to 250kHz
  • Operating Temperature Range: -40°C to +85°C
  • Package: 16-pin SOIC (DW)

Descriptions:

  • Designed for boost-type power factor correction circuits.
  • Implements average current-mode control for improved power factor and low distortion.
  • Includes a precision multiplier/divider for accurate current shaping.

Features:

  • Average Current Mode Control: Ensures low harmonic distortion.
  • Programmable Oscillator: Adjustable switching frequency.
  • Undervoltage Lockout (UVLO): Ensures proper startup and shutdown.
  • Soft-Start Function: Reduces inrush current.
  • Overvoltage Protection: Safeguards against output overvoltage.
  • Zero-Current Detection: Optimizes efficiency at light loads.

This IC is widely used in AC-DC power supplies to comply with power quality standards.
