Quick Start
Recommended Equipment
•
•
•
MAX15032 EV kit
2.9V to 5.5V, 100mA DC power supply (VIN)
Voltmeter
The EV kit can be operated with a 2.9V to 5.5V input
voltage range or a 5.5V to 11V input voltage range. By
default, the EV kit is configured to operate with a 2.9V
to 5.5V input voltage range. To operate the EV kit in
the 5.5V to 11V input range, the following configuration
changes should be made:
•
•
•
Remove capacitor C5 (0.01FF).
Connect the CP pin (U1, pin 7) to VIN.
Leave the CN pin (U1, pin 6) unconnected.
Input Voltage Range
The EV kit is fully assembled and tested. Follow the
steps below to verify board operation.
Caution: Do not
turn on the power supply until all connections are
completed.
1) Verify that a shunt is placed across pins 1-2 of jump-
er JU1 to enable the device.
2) Connect the positive terminal of the DC power supply
to the VIN pad. Connect the negative terminal of the
DC power supply to the adjacent PGND pad.
3) Connect the voltmeter across the VOUT and GND
pads.
4) Turn on the 2.9V to 5.5V DC power supply and verify
that the output is 30V.
Procedure
The EV kit is configured to provide a 30V output volt-
age. However, the output voltage can be adjusted from
(VIN + 1V) to 36V by selecting appropriate R1 and R2
values. Select R2 in the 6kI to 10kI range. R1 is then
given by:

where V

= 1.245V. For significantly different operation
points, the EV kit may require a different inductor. Refer
to the MAX15032 IC data sheet for proper component
selection.
The EV kit features a shutdown mode that reduces
the device’s quiescent current to 0.5FA. Jumper JU1
selects the shutdown mode. See Table 1 for jumper JU1
functions.
Detailed Description
The MAX15032 EV kit contains a high-efficiency pulse-
width-modulated (PWM) step-up DC-DC converter. The
MAX15032 features an adjustable output voltage and
an internal MOSFET switch to achieve a fast transient
response. The EV kit operates from a 2.9V to 5.5V DC
power supply and provides a regulated 30V output,
and has a 600mW output capability from a 2.9V input.
The EV kit is configured for a 2.9V to 5.5V input, 30V
output, and operates with a 500kHz switching frequency.
Operation at a different input voltage or output voltage
may require changes to the EV kit configuration. Refer to
the MAX15032 IC data sheet for detailed information on
device operation.
