Product Details

General Description

The AS1101/AS1102/AS1103/AS1104 are LED drivers designed to match current source bias for any color LED, including white and blue. The devices can drive up to 4 high-current LEDs, and the LED current is programmable using an external resistor (RSET). The AS1101 LED currents are 460 x ISET (per LED, typ) at an LED cathode voltage (VSAT) of 150mV and 650 x ISET (typ) at a VSAT of 1V, where ISET is the current through RSET connected to pin CTRL. The AS1102, AS1103, and AS1104 LED currents are 230 x ISET (per LED, typ) at a VSAT of 150mV and 325 x ISET (typ) at a VSAT of 1V.
