PMIC - LED Drivers, such as the MPQ4425MGQB-P, are power management integrated circuits (PMICs) optimised for driving light-emitting diodes (LEDs). They offer advanced features and performance that make them an ideal choice for lighting applications requiring high-efficiency and advanced features. The MPQ4425MGQB-P is a four-channel source driver IC in a 4 mm x 4mm x 1.2mm package that operates at a supply voltage of 17V and 3.2V to 28V.

The MPQ4425MGQB-P is designed to drive LEDs up to 8A in four independent channels, providing excellent load regulation and low ripple. It has high efficiency up to 95%, and its high switching frequency means it can operate in small-sized LEDs with minimal acoustic noise. The driver is designed to operate at a maximum temperature of 125°C and offers configurable overvoltage protection and overload protection, making it ideal for power-sensitive applications.

The IC features two operating modes: constant voltage and constant current. In constant voltage mode, the desired output voltage is set, and the driver will maintain this voltage regardless of the LED current. In constant current mode, the desired output current is set, and the driver will maintain this current to provide constant LED intensity. By using both operating modes, manufacturers can create solutions tailored to a variety of lighting applications.

The MPQ4425MGQB-P\'s advanced features also include low dropout (LDO) regulation and logic power supply (LPS) regulation. LDO regulation allows the driver to maintain steady output voltage at varying current to ensure the optimal efficacy of the LEDs. LPS regulation ensures the driver is supplied with clean and stable power, further enhancing its performance. The driver also supports soft-start, low-power sleep mode, dimming, and over-temperature protection.

The MPQ4425MGQB-P also offers excellent flexibility for LED applications. It is compatible with a wide range of LED types, such as ceramic, lead frame, and alumina. The driver is available in a variety of packages and in four different output configurations, making it suitable for a wide range of LED applications. It also has a wide input voltage range, allowing manufacturers to create solutions tailored to their needs.

The MPQ4425MGQB-P is an ideal choice for LED applications requiring advanced features and high efficiency. It has a wide input voltage range, excellent load regulation, and a variety of safety features, making it an ideal choice for power-sensitive applications. By offering excellent flexibility and adjustable operating modes, the MPQ4425MGQB-P can be used to easily create solutions tailored to a variety of lighting applications.
