LP5522 Datasheet (National Semiconductor)

LP5522, Programmable LED Driver

The LP5522 is a simple single wire programmable LED controller in six bump micro SMD package.

It provides constant current flow through high side driver.

Output current can be set from 1 mA to 20 mA by using an external resistor on the ISET pin.

If no external resistor is used, output current is set
