MAX1 5 7 5 Eva lu a t io n Kit

Ge n e ra l De s c rip t io n

Fe a t u re s

The MAX1575 evaluation kit (EV kit) is a fully assem-

bled and tested circuit for evaluating the MAX1575

white LED 1x/1.5x charge pump. The MAX1575 drives

4 white LEDs in a main display group and 2 white LEDs

in a sub-group. These 6 surface-mount white LEDs are

included on the EV kit. In addition to the LED driver cir-

cuit, the EV kit includes two pulse-generator circuits on

the left side of the PC board that are used for testing

the s ing le -wire s e ria l p uls e -d imming fe a ture of the

MAX1575.

♦ Powers 4 Main and 2 Sub-Display LEDs

♦ Average 85% Efficiency (P_LED/ P_BATT) over Li+

Battery Discharge

♦ 1.5% LED Current Matching

♦ Adaptive 1x/1.5x Mode Switchover

♦ Low Input Ripple and EMI

♦ Individual 5% to 100% Brightness Single-Wire

Serial Pulse Dimming

♦ 2.7V to 5.5V Supply Voltage Range

♦ Thin QFN 4mm x 4mm IC Package

♦ Fully Assembled and Tested
