A6275ELW集成电路（IC）的LED驱动器规格书PDF中文资料

A6275ELW属于集成电路（IC）的LED驱动器。由Allegro MicroSystems制造生产的A6275ELWLED 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。

DABiC-IV, 32-BIT SERIAL-INPUT, LATCHED SOURCE DRIVER

The A6818– devices combine a 32-bit CMOS shift register, accompanying data latches and control circuitry with bipolar sourcing outputs and pnp active pull downs. Designed primarily to drive vacuum fluorescent displays, the 60 V and -40 mA output ratings also allow these devices to be used in many other peripheral power driver applications. The A6818– features an increased data input rate (compared with the older UCN/UCQ5818–F) and a controlled output slew rate.
