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 (autorestart
/ latch-mode)
• Supports design of Class 2 drivers
• Low Bill of Materials
