MP4033GSE集成电路（IC）的LED驱动器规格书PDF中文资料

DESCRIPTION

The MP4033 is a TRIAC-dimmable primary side–control, offline LED lighting controller with active PFC. It is also available for applications that requires analog dimming with PWM input. It outputs an accurate LED current for an isolated lighting application with a single-stage converter. The proprietary real-current–control method accurately controls the LED current using primary-side information.
