MAX1572EVKIT Maxim Integrated, MAX1572EVKIT Datasheet - Page 2

• Manufacturer Part Number: MAX1572EVKIT
• Description: Power Management IC Development Tools Evaluation Kit for the MAX1572
• Manufacturer: Maxim Integrated
• Series: MAX1572r

The operating mode is selected with JU1 and JU2, as
shown in Table 1. For details on each operating mode,
refer to the MAX1572 data sheet.
A connection is provided on the MAX1572 EV kit for
evaluating the RESET output of the MAX1572. RESET is
an open-drain output with an internal 14kΩ pullup resis-
tor to OUT. Refer to the MAX1572 data sheet for details
on the operation of RESET.
An RC filter is included on the EV kit to reduce the
power-supply noise entering the IC through ABATT. To
evaluate the circuit without the filter, short R1 on the PC
board and remove C4.

The MAX1572 EV kit comes with the 1.5V output version
of the MAX1572 installed. To evaluate other voltage ver-
sions, replace the IC with the voltage version part to
evaluate. MAX1572 output voltages range from 0.75V to
2.5V. Samples of the standard versions are available
from Maxim. Refer to the MAX1572 data sheet for order-
ing information. When evaluating output voltages less
than 1.5V, replace C2 with a 22µF ceramic capacitor.
