Introduction
This document describes the AS1111C Evaluation Kit.
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.
