♦ +5V, +12V, or Adjustable Voltage
♦ Tiny Surface-Mount Design
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.
♦ 200mA Output Current
♦ +3V to +5V Input Voltage Range
♦ 1µA IC Shutdown Current
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-
♦ Up to 1MHz Switching Frequency
ate other output voltages between V and +12.5V.

♦ Fully Assembled and Tested Surface-Mount
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.

To evaluate the MAX607, turn off the power to the EV
kit. Replace L1 with a 10µH inductor and replace the
MAX606 with a MAX607EUA. No othe r ha rd wa re
changes are necessary. A good candidate for a 10µH
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).
