Introduction

This document describes the AS1111A Evaluation Kit.

The AS1111A is a LED driver designed to match current source bias for any color LED, including

white and blue. 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, type) at an LED cathode voltage (VSAT) of

150mV and 650 x ISET (type) at a VSAT of 1V, where ISET is the current through RSET connected

to pin CTRL.

The AS1111A incorporate a chip-enable feature via pin EN. When the devices is disabled, the

supply current drops down to less than 1µA. The AS1111A are available in a 6-pin WL-CSP

package with 0.4mm pitch.
