XDPL8218 Digital Flyback Controller IC XDP™ Digital Power Data Sheet Revision 1.0 Features
• Single stage flyback controller with
Power Factor Correction (PFC)

Secondary Side Regulated (SSR) Constant Voltage (CV)
output • Supports universal AC input (90 Vrms to 305 Vrms) and DC input • High power quality from 33% to 100% load, with AC input up to 277 Vrms • Typical
Power Factor (PF)
> 0.98 and
Total Harmonic Distortion (THD)
< 10% • High efficiency with
Quasi-Resonant Mode, switching in valley 1 (QRM1)
at high output power and frequency controlled
Discontinuous Conduction Mode (DCM)
at medium output power • Typical efficiency > 90% • Low standby power with
Active Burst Mode (ABM)
• Typical standby power < 100 mW (under flyback output no load condition) • Low audible noise in
ABM
• Input overvoltage and undervoltage (Brown-in / Brown-out) protection • Power limitation during brown-out, to better protect primary components from overheating and saturation • Output power limitation and output undervoltage protection • Output overvoltage protection and VCC overvoltage protection • Configurable parameters, e.g. brown-out power limitation slope, protection thresholds and reaction (auto- restart / latch-mode) • Supports design of Class 2 drivers • Low Bill of Materials
