Description
The MP4001 is a high efficiency step-down converter designed for driving the high brightness Light Emitting Diodes (LEDs).
Features
- no reverse recovery loss in the freewheeling diode, soft turn on with zero-current and valley voltage for the power MOSFET. Such operation mode can achieve very high efficiency and in the same time minimize the inductor value and size. With the boundary conduction control mode, the LED current can be well regulated by control the MOSFET peak current which is sensed through an external resistor. Its low 300mV feedback voltage reduces power loss and improves the efficiency. The MP4001 integrates a.
