The MIC4811YMM-TR is a high-efficiency linear White LED (WLED) driver designed by Microchip Technology to drive up to six WLEDs for signage lighting. This device offers high efficiency by avoiding switching losses found in traditional charge pump or inductive boost circuits. It provides six linear drivers that maintain constant current for each WLED.
The MIC4811YMM-TR features Dynamic Average Matching (DAM) for optimum matching across all WLEDs, ensuring uniform display illumination with high accuracy current regulation (±1% typical). Brightness is controlled via an Ultra Fast PWM interface, operating down to less than 1% duty cycle. The input voltage range is 3.0V to 5.5V, with a typical dropout voltage of 100mV at 50mA. Each channel can drive LED current up to 50mA.
This WLED driver is available in a 10-pin MSOP package, suitable for surface mounting. The operating junction temperature range is -40°C to +125°C. Its features make it ideal for applications such as billboard displays, marquee displays, instrument displays, and LCD display modules where consistent and controllable LED illumination is critical.
