Description

The MIC4811 is a high efficiency linear White LED (WLED) driver designed to drive up to six high current WLEDs for signage lighting. The MIC4811 provides the highest possible efficiency as this architecture has no switching losses present in traditional charge pumps or inductive boost circuits. The MIC4811 provides six linear drivers which maintain constant current for up to six WLEDs. It features a typical dropout of 100mV at 50mA.

The MIC4811 features Dynamic Average Matching™ (DAM™) which is specifically designed to provide optimum matching across all WLEDs. The high accuracy (±1% typical) current regulated WLED channels ensure uniform display illumination under all conditions. The brightness is controlled through an Ultra Fast PWM™ interface operating down to less than 1% duty cycle.

The MIC4811 is available in a 10-pin MSOP package with a junction temperature range of -40°C to +125°C
