MIC4812 - High Current 6 Channel Linear WLED Driver

Key Features

  • The MIC4812 is a high efficiency linear White LED (WLED) driver designed to drive up to six high current WLEDs for signage lighting. The MIC4812 provides the highest possible efficiency as this architecture has no switching losses present in traditional charge pumps or inductive boost circuits. The MIC4812 provides six linear drivers which maintain constant current for up to six WLEDs. It features a typical dropout of 190mV at 100mA. The MIC4812 features Dynamic Average Matching™ (DAM™) which i.

MIC4812 High Current 6 Channel Linear WLED Driver with DAM™ and Ultra Fast PWM™ Control General Description Features The MIC4812 is a high efficiency linear White LED (WLED) driver designed to drive up to six high current WLEDs for signage lighting. The MIC4812 provides the highest possible efficiency as this architecture has no switching losses present in traditional charge pumps or inductive boost circuits. The MIC4812 provides six linear drivers which maintain constant current for up to six WLEDs. It features a typical dropout of 190mV at 100mA. The MIC4812 features Dynamic Average Matching™ (DAM™) which is specifically designed to provide optimum matching across all WLEDs.
