MAX17007A Evaluation Kit
The MAX17007A EV kit can be evaluated with outputs
OUT1 and OUT2 operating in combined mode. In this
mode, the outputs are combined to support higher out-
put currents. To configure the MAX17007A for com-
bined-mode operation, place a shunt across pins 2-3 of
jumper JU3. Short OUT1 and OUT2 together with a low-
impedance copper strap. Additional configuration
requirements are listed in Table 9.
Once the EV kit is configured for combined-mode oper-
ation, the PGOOD1 output is used as the power-good
indicator. The configurable settings during combined-
mode operation are described below:

DESCRIPTION
•
•
•
•
The MAX17007A EV kit can be evaluated with dual-
package MOSFET N5. To evaluate OUT1 with a dual-
package MOSFET, remove MOSFETs N1 and N2 and
install N5. Fairchild Semiconductor’s FDS6984S is an
example of a dual-package MOSFET that fits the N5
pinout and orientation.
Output Voltage: Configured for a preset,
adjustable, or dynamic output voltage. The output
voltage is set by the voltage at REFIN1, which is set
through jumpers JU1 and JU2 (see Table 4).
Pulse-Skipping Control Input: Set by the SKIP pin
and configured through jumper JU4. When in com-
bined mode, ultrasonic mode is not supported (see
Table 6).
Per-Phase Current Limit: Set by the ILIM1 pin and
configured through jumper JU6 (see Table 7).
Switching Frequency: Set by resistor R16 (TON1).
See the Switching Frequency (f
for more details. The TON2 input is not used to set
the switching frequency, but it cannot be left open.
Install a similar value resistor in R17 (TON2) as in
R16 (TON1).
