PMIC (power management integrated circuits) are essential components used in high-efficiency and reliable LED lighting applications. The MP3399EY-LF-Z LED driver, a product of Monolithic Power Systems (MPS), is a LED driver that supports the industry\'s most extensive range of high-power LED configurations. This article will discuss the application field and working principle of the MP3399EY-LF-Z LED driver.
The MP3399EY-LF-Z is designed to support high-power LED configurations of up to 1.5A and a wide range of driving voltages from 4V to 45V. It is suitable for use in a variety of applications, such as street lights, home decorative lighting, laptop backlighting, industrial and commercial lighting, and power supplies.
In terms of its features and advantages, the MP3399EY-LF-Z is capable of providing high-performance regulation, high efficiency, and high reliability. It is also capable of providing excellent thermal efficiency and dynamic response to various temperature changes. The power good feature of this device ensures reliable operation. Additionally, the MP3399EY-LF-Z offers adjustable current control and dimming options, enabling the design of highly efficient LED lighting systems.
Moving on, it is important to understand how the MP3399EY-LF-Z works. The device is based on a constant on-time (COT) controlling principle and has a regulated constant current operation mode. COT is used to regulate the output current of an LED load, in relation to the voltage across an LED and its output current. The input voltage is compared to the voltage of the LED, and the COT is adjusted accordingly. The device allows for an adjustable, fixed frequency PWM dimming, which can be coupled with an external VIN pin for dimming control, to achieve dimming ratios of up to 1000:1. The MP3399EY-LF-Z also allows for over-temperature, soft start, and over-current protection functions.
By using a constant on-time control principle, the MP3399EY-LF-Z LED driver provides precise regulation of the output current and excellent power efficiency for high-power LED applications. Its features, such as adjustable current control, dimming options, and protection functions, make it an ideal choice for the design of efficient LED lighting systems.
