The AS1111C is a LED driver designed to match current source bias for any color LED, including white and blue. The device can drive up to 4 high-current LEDs, and the LED current is programmable using an external resistor (RSET). The AS1111C LED currents are 230 x ISET (per LED, type) at an LED cathode voltage (VSAT) of 150mV and 325 x ISET (type) at a VSAT of 1V, where ISET is the current through RSET connected to pin CTRL. The AS1111C incorporate a chip-enable feature via pin EN. When the devices are disabled, the supply current drops down to less than 1µA. The AS1111C is available in a 8lead MLPD package with 0.5mm pitch. 2 Kit Content Figure 1: Kit Content 1 Label Item Comment 1 Evaluation Board AS1111C (8lead MLPD 2x2mm package with 0.5mm pitch) 3 Getting Started Connect your supply to GND, VSET and VLED.
