Quick Start

Recommended Equipment
• MAX17116Q EV kit
• +2.3V to +4.2V, 1A power supply VIN
• Two digital voltmeters

Procedure 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
shown in Table
2 Connect the positive terminal of the power supply to the VIN PCB pad and the negative terminal to the nearest PGND PCB pad.
3 Connect the first voltmeter across the ELVDD PCB pad and the nearest PGND PCB pad.
4 Connect the second voltmeter across the ELVSS PCB pad and the nearest PGND PCB pad.
5 Turn on the DC power supply.
6 Verify that the voltmeters display VELVDD = +4.6V and VELVSS = -4.9V.

Detailed Description of Hardware

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.

Step-Up Regulator 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.

Inverting Converter The EV kit contains an inverting DC-DC converter with an integrated power MOSFET switch and synchronous rectifier. The inverting regulator output ELVSS is adjustable 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.

Enable Input and Serial Interface Input The EV kit features a 3-pin jumper JU1 to control the enable input and an EN test pad to access the serial interface 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.
