ADI LTC3220EPF#PBF

DC DC 稳压器2.9V5.5V20mA

Overview

The LTC3220/LTC3220-1 are highly integrated multi-display LED drivers. These parts contain a high efficiency, low noise charge pump to provide power to up to eighteen universal LED current sources. The LTC3220/LTC3220-1 require only five small ceramic capacitors to form a complete LED power supply and current controller.

The LTC3220/LTC3220-1 charge pump optimizes efficiency based on the voltage across the LED current sources. The part 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 parts into 1.5x mode and a subsequent dropout switches the LTC3220/LTC3220-1 into 2x mode. The parts reset to 1x mode whenever a data bit is updated via the I2C port.
