LED drivers are a type of power management integrated circuits (PMICs) that are used to optimize the amount of current supplied to an LED (light emitting diode) while minimising power consumption. In the field of LED driver applications, SGMICRO’s MIC2874YCS-TR is a highly-flexible and efficient solution for lighting control. This wide-input voltage range LED driver has a built-in boost-buck-boost regulator and advanced control features. It offers a range of features for a wide range of LED applications.

The MIC2874YCS-TR has a wide range of input voltage, from 3.3V to 18V nominal, and an operating temperature range from -40℃ to +85℃. The device operates at 500kHz, making it suitable for use in applications with high efficiency requirements. It has 3 PWM (pulse width modulation) dimming modes, and integrated soft start. Furthermore, it offers a single-stage load current regulation, double-stage current regulation and double-stage current control with a higher price point for increased efficiency.

The MIC2874YCS-TR is designed for adjustable LED applications, and offers adjustable current and brightness levels. The device has a built-in boost regulator which can supply up to 1A of current and can be adjusted from 2V to 28V. With the use of Synchronous Rectified Buck Conversion (SRBC) technology, this regulator can be set up to operate in three modes – boost, buck-boost, and synchronous rectified buck, resulting in higher efficiency. It also includes multiple safety features, such as short circuit protection, open circuit protection, over-current protection, and over-temperature protection.

In addition, the MIC2874YCS-TR has several advanced control features. It has a programmable soft-start time, peak current and frequency, as well as a 100% PWM dimming mode for dimming levels from 0% to 100%. It also has a variable brightness mode which allows users to program multiple brightness settings without having to change the input voltage. Furthermore, the device provides an accurate analog and digital dimming control for light intensity adjustment, and can be configured for either current-mode or voltage-mode operation. Finally, the device has an output voltage accuracy of 2% and a reference voltage accuracy of 2%.

The MIC2874YCS-TR is a highly-flexible and efficient device for LED driver applications. It has a wide range of features that enable it to be tailored to the needs of applications, including adjustable current and brightness levels, and support for safety features. It also offers advanced control features, such as programmable peak current and frequency, an accurate analog and digital dimming control, and support for current-mode and voltage-mode operations. All of these features make the MIC2874YCS-TR an ideal solution for lighting control applications.
