MIC2287 is a 3-channel, constant current LED driver that operates from a 4.5V to 24V input. It supports high speed, high resolution, and high accuracy dimming. With the help of the input PWM signal and high speed pulse density modulated dimming, the MIC2287 3-LED-EV allows lighting designers to create high-end, high-efficiency LED lighting systems for a wide range of applications.

The MIC2287 3-LED-EV Application Field is a great option for mid-level LED Drivers who are trying to manage three separate LEDs. Its main goal is to help with accurate digital and analog dimming. The 3-LED-EV has comprehensive protections including Overtemperature, Undervoltage Lock-Out, Overvoltage, and Overcurrent. It provides also possibilities to program LED current in two ranges and a wide range of LED output current ratios.

The Working Principle of the MIC2287 3-LED-EV is quite simple and straightforward. The device first identifies input PWM signal and PWM mode selection. Considering the dimming resistor and the current set resistor, the output current ratio is then set to current mode, which then controls the current through each LED channel. The MIC2287 3-LED-EV features also low power CMOS, high efficiency, and power-down mode which protects each LED from stress. It also provides digital dimming pulse density modulation for PWM dimming.

The MIC2287 3-LED-EV is an excellent choice for mid-level LED Drivers. It provides features that help with exact digital and analog dimming. This product offers controllability of three separate LEDs, comprehensive protections, programmable LED current in two ranges, high-efficiency power-down mode, and pulse density modulation for PWM dimming. The MIC2287 3-LED-EV is the perfect option for driving and dimming multiple LEDs in a wide range of applications.
