The Introduction of PMIC - LED Drivers

Integrated Power Management IC (PMIC) - LED drivers, which is an important development of the power electronics industry, are integrated circuits designed to provide power management solutions. These devices are usually used to drive the operation of light emitting diode (LED) or a set of LEDs. The I2C interface and efficient algorithms to meet general lighting and specialized application requirements, PMIC - LED drivers provide flexible, fast and accurate lighting control for projectors, TVs, TVs, gaming machines, tablets, mobile phones and other LED lighting LED applications.

The Definition of MP3318GC-P

MP3318GC-P is a type of PMIC - LED driver specifically designed for lighting and small motor application control. The MP3318GC-P simplifies lighting system design elimination and makes it more reliable. The MP3318GC-P is based on a 0.4V to 5.0V input voltage range and has an extremely low quiescent current of only 8.3uA. It is an integrated solution consisting of both an inductor and a 1.2MHz fixed frequency synchronous buck-boost converter to reduce the size and complexity of the application circuit.

MP3318GC-P Application Field and Working Principle

The MP3318GC-P is a high-performance, low operating voltage PMIC - LED driver designed to drive a white LED or a full set of RGB in a cost-effective manner. It is well suited to drive the white LED string to generate the desired light pattern. The MP3318GC-P can be used in a variety of applications such as camera flash, backlighting, display light and panel light. It is also suitable for automotive, industrial and home lighting applications.

The MP3318GC-P consists of an inductor, an integrated power switch and an internal feedback control loop. These components enable the device to operate in a buck-boost topology. The operating principle of the device is quite simple. The power switch is connected between the input voltage source and the inductor, and the inductor is connected to the output through two diodes. With the power switch closed, the current in the inductor builds up, and the output voltage rises until the voltage reaches the desired level. When the output voltage reaches the desired level, the power switch is opened and the inductor returns the stored energy to the load.

The MP3318GC-P provides a high-efficiency boost converter for medium current applications. It can step-up input voltage from 0.4V up to 5.0V with maximum current of 1.6A. The device is ideal for applications such as LED backlighting, flash and display lighting, automotive lighting, and panel lighting. The MP3318GC-P is also easy to configure and provides fast switching frequency.
