MP4000 - White LED Driver Controller

Name: MP4000
SKU: MP4000-1471618

MPS

Datasheet Details

The MP4000 is a high efficiency step-down converter designed for driving high brightness Light Emitting Diodes (LEDs).

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 minimize the inductor value and size. Also, the LED current can be well regulated by controlling the MOSFET peak current, which is sensed through an external resistor. Its low 300mV feedback voltage reduces power loss and improves efficiency. The MP4000 can accept an external PWM or a DC signal for the burst dimming control. The MP400.
