The MIC2844AYMT-TR from Microchip Technology is a high-efficiency linear White LED (WLED) driver designed for portable display and keypad backlighting. This device can drive up to six WLEDs, extending battery life by avoiding switching losses found in charge pumps or inductive boost circuits.
Key features include Dynamic Average Matching (DAM) for uniform display illumination with channel matching better than ±1.5% typical. The brightness is controlled via a single-wire digital interface, offering 49 steps in logarithmic scale. It operates with an input voltage range of 3.0V to 5.5V and has a typical dropout voltage of 40mV at 20mA.
The MIC2844AYMT-TR is available in a 10-pin 2mm x 2mm Thin MLF® package, suitable for surface mounting. Its operating junction temperature range is -40°C to +125°C, making it robust for various mobile applications.
This linear driver maintains constant current for each WLED, ensuring proper regulation regardless of the number of channels utilized. It is ideal for applications requiring efficient and uniform LED illumination in mobile devices.
