The MP3373GM is a multi-channel step-down LED driver IC, which is made by Monolithic Power Systems, Inc. (MPS). It is used to provide power supply to high power LEDs and commercial LED lighting. The MP3373GM is classified as a PMIC - LED Drivers (Power Management Integrated Circuit - Light Emitting Diode Drivers).

The MP3373GM LED driver IC integrates a valence power MOSFET, DCR programmable current regulator and high performance current calibrated LED driver into a 3×2mm, TDFN-12 package. The MP3373GM works as a step-down regulator, which reduces an unregulated voltage to a regulated and constant voltage for the LED. The regulated voltage can be adjusted and programmed according to the LED requirement.

The output current of the MP3373GM ranges from 10mA to 1000mA, with a typical 951.5 mV dropout voltage. The MP3373GM also has over temperature, over current, under voltage lockout and LED open LED shut-down protection features. The device has an efficiency of up to 95% and can be used in severe temperature ranges of -40°C to 125°C.

The MP3373GM is used in low voltage, high power LED lighting and commercial applications. It is ideal for small form factor designs and multi-channel LED configurations. The MP3373GM can be used in street lights, wall washers, MR16 spot lights, decorative lighting, step lighting, spotlights, tunnel lighting and area lighting.

The working principle of the MP3373GM is based on a buck regulator circuit. The input voltage is reduced to an output voltage, which is a fraction of the input. The wattage is reduced to such degree that the output is sufficient for the LED’s need. The current is regulated by the use of a shunt resistor or DCR sensing. The current set point is maintained by pulse-width modulation feedback control.

The MP3373GM LED driver IC provides a stable and efficient LED power supply for the LED lighting applications. It has features such as current adjustment, heat dissipation and over temperature protection which provide a reliable and robust platform for LED applications. The MP3373GM can be used in a variety of LED applications and is capable of handling high power LED lighting with ease.
