ADI LTC3219EUD#PBF

DC DC 稳压器2.9V5.5V28mA

Overview

The LTC3219EUD is a highly integrated multidisplay LED driver. The device contains a high efficiency, low noise charge pump to provide power to nine universal LED current sources. The LTC3219EUD requires only five small ceramic capacitors to form a complete LED power supply and current controller.

The LTC3219EUD charge pump optimizes efficiency based on the voltage across the LED current sources. The device powers up in 1x mode and will automatically switch to boost mode whenever any enabled LED current source begins to enter dropout. The first dropout switches the IC into 1.5x mode and a subsequent dropout switches the LTC3219EUD into 2x mode. The part resets to 1x mode whenever a data register is updated via the I2C port.
