General Description

The MAX17065 evaluation kit (EV kit) is a fully assem-

bled and tested surface-mount PCB that evaluates the

high-efficiency MAX17065 organic LED (OLED) driver.

The MAX17065 EV kit operates from a +2.3V to +4.5V

single power supply and includes dual switch-mode

power-supply (SMPS) outputs, one LDO, and dual reg-

ulated charge pumps for an OLED panel.

The MAX17065 EV kit provides an on-board I

C/SMBus

™

interface and is connected to the computer through the

universal serial bus (USB) port. The EV kit includes

Windows

2000/XP- and Windows Vista

-compatible

software that provides a graphical user interface (GUI)

for control of the MAX17065’s output voltages, switching

frequency, operating mode, current limit, and SMPS and

charge-pump enables.

Features

o +2.3V to +4.5V Input Range

o 85% Efficiency (VIN = +3.3V, I

MAX17065 Evaluation Kit The MAX17065 includes dual SMPS outputs (+5.35 fixed positive and -5V to -0.5V adjustable negative), one LDO (+1.9V/60mA), and dual regulated charge pumps (+5.5V to +9V positive and -5V to -0.5V negative) for an OLED panel. Shutdown Control The MAX7065 can be placed in shutdown mode through jumper JU1 (see Table 2). When connected to GND or left open, the VD output is enabled with four rising CLK edges. When connected to VDDIO, the MAX17065’s VD is enabled without a CLK signal.
