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
