Applications

* where a smaller board space is critical. The LED current is programmable from 3mA to 25mA in a 3mA step by applying digital codes at the EN/SET pin. A built-in soft-start circuit prevents a high inrush current from being drawn from the supply source during power on and 1×/1.5× mode switching. The th
