MP4021GS-A集成电路（IC）的LED驱动器规格书PDF中文资料

MP4021GS-A属于集成电路（IC）的LED驱动器。由美国芯源系统有限公司制造生产的MP4021GS-ALED 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。

DESCRIPTION

The MP4021A is a primary-side–control offline LED lighting controller that achieves high power factor and accurate LED current for isolated single-power-stage lighting applications in a single SOIC8 package. The proprietary real current control method accurately controls LED current from primary-side information. Eliminating the secondary-side feedback components and the optocoupler significantly simplifies the LED lighting system design.

• Low (1mA) quiescent current

• Input UVLO

• Cycle-by-cycle current limit

• Over-voltage protection

• Short-circuit protection

• Over-temperature protection

• Available in an SOIC8 package

APPLICATIONS

• Solid-state lighting

• Industrial and commercial lighting

• Residential lighting
