The MIC4812YMME from Microchip Technology is a high-efficiency linear White LED (WLED) driver. It is designed to drive up to six high-current WLEDs, making it suitable for signage lighting applications like billboard and marquee displays.
This device features six independent linear drivers that maintain constant current for each WLED. It operates with an input voltage range of 3.0V to 5.5V and can deliver up to 100mA per channel. The driver boasts a typical dropout voltage of 190mV at 100mA and provides high accuracy current regulation, better than ±1% typical.
Brightness control is managed through an Ultra Fast PWM™ interface, operating down to less than 1% duty cycle. The MIC4812 also incorporates Dynamic Average Matching™ (DAM™) for optimal matching across all WLEDs, ensuring uniform display illumination. The component is housed in a 10-pin MSOP ePad package and operates within a junction temperature range of -40°C to +125°C.
Key features include high efficiency due to its linear architecture, eliminating switching losses. It supports a wide PWM frequency range from 200Hz to 500kHz. The MIC4812 maintains proper regulation regardless of the number of channels utilized, offering design flexibility.
