A8530规格书详情
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
A8530属于集成电路(IC) > LED 驱动器。Allegro MicroSystems制造生产的A8530LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列,可通过标称固定电压的电源为负载(通常为发光二极管)提供电流,并且电流可控。它与用于电压调节的类似产品的主要区别在于,这类器件提供较低的反馈电压(以提高系统能效),而且通常可对器件工作点进行外部控制,可在照明应用中用于实现调光功能。
