MAX606 Evaluation Kit
________________ General Description
The MAX606 evaluation kit (EV kit) provides a regulated
+5V output voltage at up to 200mA while operating
from a +3V to +5V input voltage. The MAX606 operates
at frequencies up to 1MHz, allowing the use of small
external components.
The MAX606 EV kit is a fully assembled and tested, sur-
face-mount printed circuit board. It comes with the out-
put voltage set to +5V, but can also be used to evalu-
ate other output voltages between V
IN
and +12.5V.
The MAX606 EV kit can also be used to evaluate the
MAX607, which operates at 500kHz. Simply order a free
sample of the MAX607EUA along with the MAX606 EV kit.

_________________________ Quick Start
The MAX606 EV kit is fully assembled and tested.
Follow these steps to verify board operation.
Do not
turn on the power supply until all connections are
completed.
1) Connect a +3V to +5V power supply to the pad
marked VIN. The ground connects to the GND pad.
2) Connect a voltmeter and load (if any) to the VOUT
pad.
3) Make sure that JU1 is shunted.
4) Turn on the power and verify that the output voltage
is +5V.
5) Refer to the
Other Output Voltages
section to modify
the board for different output voltages.
Evaluating the MAX607
To evaluate the MAX607, turn off the power to the EV
kit. Replace L1 with a 10碌H inductor and replace the
MAX606 with a MAX607EUA. No other hardware
changes are necessary. A good candidate for a 10碌H
inductor is a Sumida CLS62-100, which fits the same
footprint as the CLS62B-5R0. Note that the CLS62-100
has a maximum current rating of 700mA, rather than 1A
for the CLS62B-5R0.
*This
capacitor is used to reduce ringing caused by lead induc-
tance of the external power supplies. It is typically not needed in
the production circuit (refer to the MAX606 data sheet for more
information).
