The MP4060 is a TRIAC-dimmable, primary side control LED controller enables single stage AC to DC LED driver with excellent dimming performance. The dimming control method is optimized for high input AC voltages ranging from 200VAC to 265VAC.
The MP4060 implements power-factor correction and works in boundary-conduction mode to reduce MOSFET switching losses.
The adaptive dimmer type detection and phase-cut-based dimming control achieves good dimmer compatibility and a deep dimming range.
The active bleeder control circuit is integrated in BD pin to simplify the external bleeder design.
The MP4060 has an integrated charging circuit at the supply pin for fast start-up without a perceptible delay.
With the unique control of the driver DIM pin, the MP4060 supports color temperature and brightness control for warm sunset dimming application.
The MP4060 has multiple protection features that greatly enhance system reliability and safety including output over-voltage protection, output short-circuit protection, winding short-circuit protection, integrated thermal foldback, supply-pin under-voltage lockout, and over-temperature protection. All of the fault protections feature auto-restart.
The MP4060 is available in SOIC-8 / MSOP-10 packages.
