A8500規(guī)格書詳情
A8500屬于集成電路(IC)的LED驅(qū)動(dòng)器。由Allegro MicroSystems制造生產(chǎn)的A8500LED 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??蓪?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。
Description
The A8500 is a multi-output WLED driver for medium display backlighting. The A8500 integrates a boost converter and eight current-sinks to provide a flexible WLED/RGB backlight driver. The boost converter can provide output voltage up to 47 V. The flexible channel selection control and high voltage capability allow a wide range of LED backlight applications. The A8500 can support any application requiring 4 to 96 WLEDs. The boost converter is a constant frequency current-mode converter.
Features and Benefits
? Active current sharing between LED strings for ±1.5 typical current matching and ±1.2 typical accuracy
? Drive up to 12 series × 8 parallel = 96 LEDs (Vf = 3.2 V, If = 20 mA)
? Flexible dimming, using alternative methods:
? LED duty cycle control (PWM pin)
? DC current using serial programming (EN pin)
? DC current using external PWM signal (APWM pin)
? An external resistor
? Boost converter with integrated 50 V, 2 A DMOS
? LED sinks rated for 30 mA
? 200 kHz to 2 MHz switching frequency
? Open LED disconnect
? Boost current limit, thermal shutdown, and soft start
? No audible ceramic capacitor noise during PWM dimming
? Adjustable overvoltage protection (OVP)
? No pull-up resistors required for LED modules that use ESD capacitors
Applications include:
? Thin notebook displays
? LCD TV
? RGB backlight
? GPS systems
? Portable DVD players
