The MAX17007A EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supplies until all
connections are completed.
1) Ensure that the EV kit is connected correctly to the
2) Verify that shunts are installed according to Table 1.
3) Turn on battery power prior to 5V DC bias power;
4) Verify that the PGOOD1 and PGOOD2 LEDs (D3
The MAX17007A EV kit demonstrates the features of
the MAX17007A dual step-down controller. The EV kit
provides a dynamic 1V/1.2V OUT1 voltage and a preset
1.5V OUT2 voltage from a 7V to 24V input. Each output
provides up to a 12A load current. The OUT1 and
OUT2 outputs are configured to operate at switching
frequencies of 270kHz and 330kHz, respectively.

Note: JU6 (ILIM1) and JU5 (ILIM2) are prewired for current
limits of 30mV.

The OUT1 output can also be configured for a preset
1.05V (REFIN1 = VDD), adjustable between 0 to 2V, or
different dynamic output voltages. The OUT2 output
can be configured for preset 1.5V (FB2 = REF) or
adjustable from 0.7V to 2V by installing appropriate
feedback resistors. See the OUT1 Voltage (V
OUT2 Voltage (V
The outputs can also be combined to operate as a two-
phase, high-current, single-output regulator. In this
mode the output is configured for either a preset,
adjustable, or dynamically adjustable output voltage
using REFIN1. See the Combined-Mode Operation sec-
tion for more details.
The MAX17007A EV kit provides access to the device’s
enable control pins (EN1 and EN2), through jumpers
JU7 and JU8, respectively. EN1 is used to control the
OUT1 output and EN2 is used to control the OUT2 out-
put. When in combined mode, EN1 is used for output
control and EN2 must be connected to GND. Tables 2
and 3 list the selectable jumper options for each output-
enable pin.
The EN1 and EN2 control pins can also be driven by an
external signal by removing the shunt from JU7 or JU8
and connecting the control signal to the EN1 or EN2
test point. The output operation will depend on the
external control-signal level.
