MP4001 Universal Input High Brightness White LED Driver DESCRIPTION FEATURES The MP4001 is a high efficiency step-down Constant-current LED Driver converter designed for driving the high Universal AC Input (85VAC-305VAC) brightness Light Emitting Diodes (LEDs). Power MOSFET Zero-Current Turn On The MP4001 drives external MOSFET with High Efficiency Boundary Mode Operation boundary conduction mode which features no Integrated High-voltage Smart LDO reverse recovery loss in the freewheeling diode, Low 1mA Operation Current soft turn on with zero-current and valley voltage PWM or DC Input Burst Dimming Control for the power MOSFET. Such operation mode Hiccup Short Circuit Protection can achieve very high efficiency and in the Maxim Frequency Limited to 110kHz same time minimize the inductor value and Thermal Shutdown size. With the boundary conduction control Available in SOIC8 Package mode, the LED current can be well regulated by control the MOSFET peak current which is APPLICATIONS sensed through an external resistor. Its low Non-Isolated Lighting 300mV feedback voltage reduces power loss General Illumination and improves the efficiency. Industrial Lighting The MP4001 integrates a high-voltage smart Automotive/ Decorative LED Lighting LDO, which allows the AC input to power up the LCD TV Backlighting IC directly. The smart LDO sinks current when DC/DC or AC/DC LED Driver Applications the input voltage is lower than 24V to achieve All MPS parts are lead-free and adhere to the RoHS directive.
