MP4000DS controller equivalent, white led driver controller.
no reverse recovery loss in the freewheeling diode and soft turn on for the power MOSFET. Such operation mode can achieve very high efficiency and at the same time minimi.
* DC/DC or AC/DC LED Driver applications
* General Illumination
* Industrial Lighting
* Automotive/ Deco.
The MP4000 is a high efficiency step-down converter designed for driving high brightness Light Emitting Diodes (LEDs).
The MP4000 drives an external MOSFET in the floating buck converter structure. The inductor current is regulated with boundary cond.
