High Efficiency 6-Channel Linear WLED Driver with DAM™ and Ultra Fast PWM™ Control

The MIC2843A is a high efficiency linear White LED (WLED) driver designed to drive up to six WLEDs, greatly extending battery life for portable display backlighting keypad backlighting, and camera flash in mobile devices. The MIC2843A provides the highest possible efficiency as this architecture has • High efficiency (no voltage boost losses)\n• Dynamic Average Matching™ (DAM™)\n• Ultra Fast PWM™ control (200Hz to 500kHz)\n• Input voltage range: 3.0V to 5.5V\n• Dropout of 40mV at 20mA\n• Matching better than ±1.5% (typical)\n• Current accuracy better than ±1.5% (typical)\n• Maintains pr;
