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 jumper JU1 is in the default position, as
2) Connect the positive terminal of the power supply
3) Connect the first voltmeter across the ELVDD PCB
4) Connect the second voltmeter across the ELVSS PCB
5) Turn on the DC power supply.
6) Verify that the voltmeters display V
The MAX17116Q EV kit includes two current-mode
1.4MHz SMPS regulators for AMOLED displays.
The positive supply is provided by a step-up regulator with
a synchronous rectifier. The negative supply is provided

by an inverting regulator with a synchronous rectifier.
The step-up regulator output is a fixed voltage of +4.6V
and the inverting regulator output is adjustable from -5.4V
to -1.5V through the single-wire EN serial interface. The EV
kit operates from a +2.3V to +4.2V single power supply.
The EV kit includes a step-up DC-DC converter with
integrated power MOSFET switch and synchronous
rectifier. The step-up regulator output (ELVDD) has a
fixed voltage of +4.6V and can provide an output current
of 250mA.
The EV kit contains an inverting DC-DC converter with
an integrated power MOSFET switch and synchronous
rectifier. The inverting regulator output (ELVSS) is adjust-
able from -5.4V to -1.5V and can provide an output
current of 250mA. The ELVSS output voltage can be
adjusted through the single-wire EN serial interface.
The EV kit features a 3-pin jumper (JU1) to control the
enable input and an EN test pad to access the serial inter-
face input. Connect EN to IN for normal operation. Connect
EN to AGND to place the device into shutdown mode.
The enable pin is also used as a serial-interface input
to adjust the inverting converter output voltage. With
no shunts installed on jumper JU1, connect an external
pulse generator at the EN test pad and send the required
serial pulses. Refer to the EN Serial Interface section in
the MAX17116 IC data sheet for a more detailed descrip-
tion. Table 1 lists the selectable jumper options.
