XDPL8218集成電路（IC）的LED驅(qū)動(dòng)器規(guī)格書(shū)PDF中文資料

XDPL8218屬于集成電路（IC）的LED驅(qū)動(dòng)器。由英飛凌科技股份公司制造生產(chǎn)的XDPL8218LED 驅(qū)動(dòng)器器件屬于 LED 驅(qū)動(dòng)器電源管理集成電路 (PMIC) 系列，可通過(guò)標(biāo)稱固定電壓的電源為負(fù)載（通常為發(fā)光二極管）提供電流，并且電流可控。它與用于電壓調(diào)節(jié)的類似產(chǎn)品的主要區(qū)別在于，這類器件提供較低的反饋電壓（以提高系統(tǒng)能效），而且通常可對(duì)器件工作點(diǎn)進(jìn)行外部控制，可在照明應(yīng)用中用于實(shí)現(xiàn)調(diào)光功能。

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
