XDPL8220 Digital PFC+Flyback Controller IC
XDP™ Digital Power
Data Sheet
Revision 1.0
Quality Requirement Category: Industrial
Features
• Universal AC input (90 - 305 VAC) or DC input (90 - 305 VDC)
• Applicable power range of 20 W to 150 W
• Small number of external parts optimizes Bill of Materials (BOM) and form factor
• High efficiency (> 90%)
• Multicontrol mode (Constant Current (CC)/Constant Voltage (CV)/Limited Power (LP)) reduces required
product variety
• Important parameters can be configured after manufacturing
• Low harmonic distortion (Total Harmonic Distortion (THD) < 15%)
• Low output ripple current
• Integrated startup cell ensures fast time to light (< 250 ms)
• Adaptive Temperature Protection
• Ambient operating temperature -40 °C to 85 °C
• Automatic switching between Quasi-Resonant Mode (QRM) and Discontinuous Conduction Mode (DCM)
• Wide output voltage range
• Pulse Width Modulation (PWM) dimming control
• Output dimming by analog reduction of driving current down to 5%
For safe operation, the XDPL8220 contains a comprehensive set of protection features:
• Output overvoltage protection (open load)
• Output undervoltage protection (output short)
• VCC over- and undervoltage lockout
• Input over- and undervoltage protection
• Bus over- and undervoltage protection
• Overcurrent protection for Power Factor Correction (PFC) and Flyback (FB) stage
Applications
• Integrated Electronic Control Gear (ECG) for Light Emitting Diode (LED) luminaires

Input Voltage Sensing
The input voltage is sensed using the HV pin.
The input voltage is used for protection, to generate AC zero-crossing signals and to detect the AC/DC source.
