Monolithic Power Systems, Inc. LED Drivers MP4060GK-Z

The MP4060GK-Z is a TRIAC-dimmable LED controller designed for high line input voltages ranging from 200VAC to 265VAC. It features primary-side control, eliminating the need for a secondary-side feedback circuit, which simplifies design. The device supports adaptive dimmer type detection and phase-cut-based dimming control, ensuring good compatibility with various dimmers and a deep dimming range. This LED driver incorporates several protective features, including output over-voltage protection, output short-circuit protection, winding short-circuit protection, and over-temperature protection, all with auto-restart functionality. It also includes an integrated thermal current foldback mechanism to extend LED lifespan and a fast start-up capability without perceptible delay. The MP4060GK-Z is suitable for applications in solid-state lighting, industrial and commercial lighting, and residential lighting, with a maximum output power of 50W. It is available in MSOP-10 packages and adheres to RoHS directives, ensuring it is lead-free and halogen-free.
