There are a variety of applications for LED drivers, such as automotive lighting, architectural lighting, industrial lighting, and consumer electronics. PMIC-LED (Power Management IC - LED) Drivers, such as the MPQ3386DR-LF-P, are integral parts of any illumination system they help to power, as they can enhance system efficiency, reduce design complexities, and improve safety and reliability in the applications.

The MPQ3386DR-LF-P, from Monolithic Power Systems (MPS), is a low voltage high efficiency main buck-boost LED driver with variable switching frequency and input & output current sensing. This device is designed for automotive interior, exterior and display lighting applications, including lighting in overhead and gloveboxes, hazard indicators, side view mirrors, CUV/SUV headlamps, and LED-backlit LCD displays.

The MPQ3386DR-LF-P LED Driver is a configurable buck-boost converter with Wide Voltage Range Input (3 V to 42 V). It includes I²C-controlled dimming and a safety shutdown pin. It can automatically detect whether it is working in buck or boost mode. It features a wide output voltage range (0 V to 42 V) and low standby current. It also has over-temperature protection and current limit protection to protect the LEDs as well as the system.

The driver offers a range of configurations, including maximum input voltage, switch frequency, dimming type, dimming range, and external sense option. It is programmed and controlled by connecting with a Smartphone or an external microcontroller via I²C. The device also has a low quiescent current and output voltage ripple for low noise operation. The dimming feature allows the user to adjust the intensity of the LED, and the safety shutdown pin helps protect the system from getting overloaded.

When used in automobile applications, the MPQ3386DR-LF-P is used to drive high-power LEDs like COB LEDs. The buck-boost topology and wide input voltage range allows the device to produce a stable output voltage, regardless of whether the input power supply is higher or lower than the output voltage. By adjusting the switching frequency, the device can automatically optimize its performance and minimize losses due to switching and conduction.

The working principle of the MPQ3386DR-LF-P LED Driver is based on the buck-boost topology. The MPQ3386DR-LF-P is a type of switching regulator with an input current sense and output current sense, allowing the power device to control both the input and output current waveforms. In buck mode, the device can accept a higher voltage than the output voltage level, whereas in boost mode it can accept lower voltage than the output voltage level. The MPQ3386DR-LF-P also has a programmable over-current protection and over-temperature protection that ensures safety when driving the LEDs.

The MPQ3386DR-LF-P LED Driver provides a unique combination of features and performance that make it easy to use in automotive, industrial and consumer electronic applications. It is a cost-effective solution for driving LED displays, panel lights, and LED backlit LCD displays, that requires fewer external components and offers less power loss than other LED Driver solutions. The MPQ3386DR-LF-P is ideal for automotive exterior, interior and display lighting applications. It is a reliable, efficient and cost-effective solution for automotive LED lighting.
