Description

FULL DATA SHEET (PDF, 112kB) Download   E-Mail The MAX1582 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX1582 white LED step-up converter. The circuit operates from 2.6V to 5.5V and delivers 0 to 20mA to light a series of up to six white LEDs. The evaluation kit has two groups of white LEDs—a main group with four LEDs, and a subgroup with two LEDs. These two groups of LEDs have independent shutdown/enable control through jumpers provided on the board. A flexible dimming feature allows the LED brightness to be controlled with either an analog voltage or a PWM signal.
