MAX1553 Evaluation Kit
General Description
The MAX1553 evaluation kit (EV kit) is a fully assem-
bled and tested circuit board with two complete cir-
cuits for evaluating the MAX1553 and MAX1554 white
LED step-up converters. The MAX1553 circuit operates
from 2.7V to 5.5V and delivers an adjustable 0 to 20mA
to drive up to six white LEDs connected in series. The
MAX1554 circuit operates from 3.15V to 5.5V and deliv-
ers an adjustable 0 to 20mA for driving up to 10 white
LEDs in series.
Features
o Constant Current Regulation for Even LED
Illumination
o Up to 88% Efficiency Driving Six LEDs
o Analog or PWM Dimming Control of LED Intensity
o Small, Low-Profile Components
o 2.7V to 5.5V Input Range
o Tiny TDFN 3mm x 3mm IC Package
o Fully Assembled and Tested
