AS1111C standard board ams eval kit manual page 3 [v 1 - 00 ] 2015 - jan - 20 document feedback 1 introduction this document descr ibes the AS1111C ev aluation kit. the AS1111C is a led driver designed to match current source bias for any color led, including white and blu e. 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 ise t is the current thro ugh rset connected to pin ctrl. the as1111 c incorporate a chip - enable feature via pin en. when the devices are disabled, the supply current drops down to less than 1 a. the AS1111C is available in a 8 lead mlpd package with 0. 5 mm pitc h. 2 kit content figure 1: kit content label item comment 1 evaluation board AS1111C ( 8lead mlpd 2x2mm package with 0.5 mm pitch ) 3 getting started connect your supply to gnd, vset and vled. be shure that the jumpers are set like you can see in the hardware description below. 1
