Digital PFC+Flyback Controller IC

Overview

TopologyPower Factor Correction
Input voltage120-227 V
Switching frequency500-2000 kHz
Output 148 V
IC revision1.1

Description

The XDPL8221 connects a digital quasi-resonant PFC XDP™ control stage and a quasi-resonant flyback controller with primary-side regulation. A serial communication interface supports direct communication with an external microcontroller unit (MCU). The XDPL8221 digital control IC is especially designed for advanced LED drivers in smart lighting or Internet of Things (IoT) applications. The built-in algorithms of the dual stage topology ensures flicker-free operation and dimming down to 1% of nominal current.

Features

  • Supports AC and DC input
  • Nominal input voltage range 100VAC – 277VAC or 127VDC – 430VDC
  • Reference board efficiency >90%
  • Power factor >0.9 and THD <15% over wide load range
  • UART interface and command set
  • Standby power <100mW
  • Temperature guard with adaptive thermal management with internal and/or external sensor
  • Digital control selects automatically best mode of operation, depending on actual requirements
    • QRM (quasi-resonant mode)
    • DCM (discontinuous conduction mode)
    • ABM (active burst mode)
  • Tunable, digital parameters
  • Configurable brown-out and brown-in protections
  • Relevant error conditions are monitored and protected
    • Undervoltage
    • Overvoltage
    • Open load
    • Output shorted

Typical applications

  • Flicker-free LED driver for indoor or outdoor applications / Multi-mode LED driver for connected lighting / Wired or wireless connected LED driver
