XDPL8210 Digital Flyback Controller IC XDP™ Digital Power Datasheet Revision 1.0 Features
• Single stage flyback controller with
Power Factor Correction (PFC)
• Primary side regulated
Constant Current (CC)
output with high precision • Supports universal AC input (90 Vrms to 305 Vrms) and DC input (127 V to 432 V) • Supports wide LED load voltage range (up to 4 times of the minimum LED load voltage) • Excellent line and load regulation (typical within +/- 2%) • High power quality (Typical
Power Factor (PF)
up to 0.99 and
Total Harmonic Distortion (THD)
< 10%) • High efficiency with
Quasi-Resonant Mode, switching in first valley (QRM1)
at high output power and frequency controlled
Discontinuous Conduction Mode (DCM)
at medium output power • Dim-to-off operation (with typical standby power as low as 60 mW) • Dedicated PWM input pin for dimming control by either a micro-controller or a transformer-less IEC60929- compliant isolated 0 - 10 V dimming circuit (based on CDM10VD) • Dimming down to 1% •
Limited Power (LP)
mode • Input overvoltage and undervoltage (Brown-in/Brown-out) protection with configurable threshold for output on/off • Brown-out maximum power reduction, to better protect primary components from overheating and saturation • Adaptive output overvoltage protection to meet UL1310 standard (Class 2) for the 54 V LED driver design. • Output and VCC undervoltage protection • Configurable dimming parameters, e.g. dimming curve (linear/quadratic), minimum current, dim-to-off option (enabled/disabled)
