The MIC4812YMME-TR is a high-efficiency linear White LED (WLED) driver from Microchip Technology, designed to drive up to six high-current WLEDs for signage lighting. This architecture offers high efficiency by avoiding switching losses found in traditional charge pumps or inductive boost circuits. The device provides six linear drivers that maintain constant current for up to six WLEDs, with a typical dropout of 190mV at 100mA.
Key features include Dynamic Average Matching (DAM) for optimum matching across all WLEDs and high accuracy (±1% typical) current regulation for uniform display illumination. Brightness is controlled via an Ultra Fast PWM interface operating from 200Hz to 500kHz, down to less than 1% duty cycle. The input voltage range is 3.0V to 5.5V, and the LED current range is up to 100mA per channel, programmable with an external resistor.
The MIC4812YMME-TR is available in a 10-pin MSOP ePad package, suitable for surface mounting. It operates within a junction temperature range of -40°C to +125°C. Applications include billboard displays, marquee displays, instrument displays, and LCD display modules.
