MAX17088 Evaluation Kit/
Evaluation System
Evluate:MAX1708
General Description
Features
o +1.8V to +6V Input Range
o Output Voltages
The MAX17088 evaluation system (EV system) consists of
the MAX17088 evaluation kit (EV kit) and the Maxim
CMAXQUSB command module. Windows® 2000/XP®- and
Windows Vista®-compatible software is also available for
use with the EV system (MAX17088EVCMAXQU+) and can
be downloaded from www.maxim-ic.com/evkitsoftware.
+8V Output at 300mA (+2.2V Input Step-Up
Switching Regulator)
+21V Output at 20mA (Positive Charge Pump)
-13V Output at 20mA (Negative Charge Pump)
1ꢀ0mA ꢁigh-Current Op-Amp Output
The MAX17088 EV kit (MAX17088EVKIT+) is a fully
assembled and tested surface-mount PCB that pro-
vides the features required for active-matrix, thin-film
transistor (TFT) liquid-crystal displays (LCDs). The EV
kit contains a step-up switching regulator, positive two-
stage charge pump, negative two-stage charge pump,
digitally adjustable VCOM calibration device with non-
volatile memory, SMBus™-compatible interface, high-
speed operational amplifier (op amp), and high-volt-
age, level-shifting scan driver for TFT-LCD applications.
o Resistor-Adjustable Switching Regulator and
Op-Amp Output Range
o Digitally Programmable Op-Amp Output Voltage
o +3ꢀV to -2ꢀV ꢁigh-Voltage Level-Shifting Drivers
o > 8ꢀ% Efficiency (Step-Up Switching Regulator)
o 1.2Mꢁz Step-Up Switching Frequency
o SMBus-Compatible Interface
o Windows 2000/XP- and Windows Vista
The MAX17088 EV kit operates from a DC supply volt-
age from +1.8V to +6V. The step-up switching regulator
is configured for a +8V output providing at least 300mA
from a +2.2V input. The positive charge pump is config-
ured for a +21V output providing at least 20mA. The
negative charge pump is configured for a -13V output
providing at least 20mA. The op amp is capable of pro-
viding up to 1ꢀ0mA peak and features a programma-
ble output voltage initially configured for +3.2V. The
high-voltage level-shifting scan driver buffers inputs
from STV, CPV, and OE pads and shifts them to a
desired level to drive TFT-LCD row logic.
(32-Bit)-Compatible Software
o 1.ꢀmm Low-Profile Surface-Mount Components
o Lead(Pb)-Free and RoꢁS Compliant
o Fully Assembled and Tested

EV System
The MAX17088 EV kit demonstrates low quiescent cur-
rent and high efficiency (> 8ꢀ%) for maximum battery
time per charge. Operation at 1.2MHz allows the use of
tiny surface-mount components. The MAX17088 36-pin
thin QFN package (0.8mm max height), with low-profile
external components, allow this circuit to be less than
1.ꢀmm high.
+Denotes lead(Pb)-free and RoHS compliant.
Note: The Maxim command module (CMAXQUSB) is required
when using the MAX17088 EV kit software.
Component List
The Maxim CMAXQUSB command module provides
the SMBus-compatible interface and is connected to a
PC through the universal serial bus (USB) port. The
MAX17088 EV kit software provides a graphical user
interface (GUI) for exercising the MAX17088 features.
