The MIC4812YMME is a high performance, off-line LED driver from Microchip Technology. This high-brightness LED driver features an externally adjustable current limit, an over-temperature circuit, and an output short-to-ground protection circuit. The MIC4812YMME is designed for off-line LED lighting applications.

The MIC4812YMME is part of a family of high-performance, multi-function linear and switch-mode power regulators that have advanced features such as adjustable current limit, over-temperature protection, and power dissipation. This device provides an ideal solution for application that require high efficiency, low cost, and robust operation.

The MIC4812YMME is an off-line driver, which uses a buck topology with two current paths and two outputs. The two outputs are for two parallel LEDs, which can be used to drive two different brightness levels. The two output currents are limited and regulated by the external current limit resistor. The current limit resistor can be adjusted to achieve desired LED current levels at different LED forward voltages between 4V and 40V.

The MIC4812YMME can operate over a wide operating temperature range and can drive up to 2.6A total LED current without the need for external heatsinks and cooling, making it ideal for single stage, multi-channel LED lighting applications. The device also offers a low-side output short-to-ground protection with an internal current limit circuit and has an efficient power transfer under all operating conditions. In addition, the MIC4812YMME can also be used in buck converters for applications that require high efficiency and low cost.

The MIC4812YMME is designed for a wide range of applications, including commercial, industrial and residential LED lighting, automotive LED applications, general electronic lighting and signage, off-grid lighting and solar photovoltaic applications, and mobile device backlighting. This device is designed for limited space, and is suitable for use in complex small form factor lighting designs. The MIC4812YMME is also ideal for high-density lighting applications due to its compact size and low power consumption.

The MIC4812YMME is a high-performance, off-line LED driver that offers excellent performance in a wide variety of challenging applications. Its feature set includes adjustable current limit, over-temperature circuit and output short-to-ground protection, making it an ideal solution for both cost and efficiency-conscious lighting designs. The device is suitable for a wide range of applications, including commercial, industrial, and residential LED lighting, automotive LED applications, general electronic lighting and signage, off-grid lighting and solar photovoltaic applications, and mobile device backlighting.
