General Description
The MAX1573 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board. The EV kit con-
tains the MAX1573, a white LED driver with a high-effi-
ciency charge pump. The EV kit accepts a 2.7V to 5.5V
input voltage and drives up to 4 white LEDs with regu-
lated constant current for uniform intensity. The
MAX1573 runs at 1MHz fixed frequency, allowing tiny
external components. An EV kit is available for both the
UCSP and the TQFN packages.

Quick Start
Recommended Equipment
For evaluation of either EV kit:
Variable-output power supply capable of supplying
up to +5.5V at 300mA
Procedure
The MAX1573 EV kit is fully assembled and tested.
Perform the following steps to verify board operation.
Do not turn on the power supply until all connec-
tions are completed:
1) Verify that shunts are across pins 1 and 2 of JU1
(EN1) and JU2 (EN2).
2) Preset the power supply to 2.7V and turn off.
3) Connect the positive lead of the power supply to the
VIN pad on the EV kit board. Connect the ground
lead of the power supply to the GND pad directly
below the VIN pad.
4) Turn on the power supply.
5) Verify that all 4 white LEDs are on with uniform
intensity.
