A8530EESTR-T規(guī)格書詳情
A8530EESTR-T屬于集成電路(IC)的LED驅(qū)動(dòng)器。由Allegro MicroSystems制造生產(chǎn)的A8530EESTR-TLED 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ζ骷ぷ鼽c(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 A8530 high efficiency charge pump ICs offer a simple, low-cost white LED driver solution for driving four display backlight and two flash/torch/video mode white LEDs. Using a proprietary control scheme (1×, 1.5×, and 2×), the A8530 can deliver well-matched LED current while maintaining the highest efficiency and low EMI. The LED current is regulated over the entire range of Li+ battery voltage to provide uniform intensity.
LED brightness and on/off can be controlled for 4 display backlight LEDs and 2 flash/torch LEDs through 2 single-wire serial interface pins.
Features and Benefits
? Proprietary adaptive control scheme (1×, 1.5×, 2×)
? 0.5 typical LED current matching
? 2 separate serial interfaces for dimming control
? Drives up to 6 white LEDs (4 display backlight, 2 flash/torch)
? 30 mA per LED channel for display backlight
? 100 mA per LED channel for flash/torch backlight
? 320 mA total output current capability
? Low EMI design and soft-start function
? Short circuit, overvoltage, thermal shutdown protection
? 0.75 mm very thin profile, 3 mm × 3 mm package
Applications include:
? White LED backlights for cellular phones, PDAs
? Digital cameras, camcorders
? Other portable device white LED backlighting
? 320 mA WLED flash/torch
