AS1111A standard board ams eval kit manual p age 3 [v 1 - 00 ] 2015 - jan - 20 document feedback 1 introduction this document describes the AS1111A ev aluation kit. the AS1111A is a led driver designed to match current source bias for any color led, including white and blu e. the devices can drive up to 2 high - current leds, and the led current is programmable using an external resistor (rset). the AS1111A led currents are 460 x iset (per led, t ype ) at an led cathode voltage (vsat) of 150mv and 650 x iset ( type ) at a vsat of 1v, where iset is the current thro ugh rset connected to pin ctrl. the as1111 a incorporate a chip - enable feature via pin en. when the devices is disabled, the supply current d rops down to less than 1 a. the AS1111A are available in a 6 - pin wl - csp package with 0.4mm pitch. 2 kit content figure 1: kit content label item comment 1 evaluation board AS1111A ( 6 - pin wl - csp package with 0.4mm 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
