Evaluates: MAX17094 19-4451 Rev 0 2/09 MAX17094 Evaluation Kit General Description Features The MAX17094 evaluation kit (EV kit) is a fully assem- +1.8V to +5.5V Input Range bled and tested surface-mount PCB that provides the Adjustable 450kHz to 1.2MHz Step-Up Switching voltages and features required for active-matrix, thin- Frequency film transistor (TFT), liquid-crystal displays (LCDs). The Output Voltages EV kit contains a high-performance step-up switching +8V Output at 300mA (Step-Up Switching regulator, a 250mA low-dropout (LDO) linear regulator, Regulator) a high-speed op amp, a digitally adjustable VCOM cali- +21.5V Output at 30mA (Positive Charge Pump) brator, and seven high-voltage level-shifting buffers for -6.5V Output at 30mA (Negative Charge Pump) scan-driver applications. +2.5V at 250mA (Linear Regulator) The EV kit operates from a DC supply voltage from 150mA High-Current Op-Amp Output +1.8V to +5.5V. The step-up switching regulator is con- Resistor-Adjustable Switching Regulator and Op- figured for a +8V output providing at least 300mA from Amp Output Range a +2.5V input. The positive charge pump is configured for a +21.5V output providing up to 30mA. The negative Digitally Programmable Op-Amp Output Voltage charge pump is configured for a -6.5V output providing +30V to -10V High-Voltage Level-Shifting Drivers up to 30mA. The op amp is capable of providing up to > 85% Efficiency (Step-Up Switching Regulator) 150mA peak and features a programmable output 2 voltage initially configured for +3.2V. The low-voltage, On-Board I C/SMBus Interface Control through low-dropout linear regulator can provide at least USB 250mA. The high-voltage, level-shifting scan driver Windows 2000/XP- and Windows Vista (32-Bit)- buffers seven logic inputs and shifts them to a desired Compatible Software level to drive TFT LCD row logic. 2mm Low-Profile Surface-Mount Components The MAX17094 EV kit demonstrates low quiescent cur- Lead(Pb)-Free and RoHS Compliant rent and high efficiency (> 85%) for maximum battery life. Operation at 1.2MHz allows the use of tiny surface- Fully Assembled and Tested mount components. The MAX17094 thin QFN package (0.8mm max height), with low-profile external compo- nents, allows this circuit to be less than 2mm high. Ordering Information 2 The MAX17094 EV kit provides an on-board I C/ PART TYPE SMBus interface and connects to the computer through MAX17094EVKIT+ EV Kit the universal serial bus (USB) port. The EV kit includes Windows 2000/XP and Windows Vista -compatible +Denotes lead(Pb)-free and RoHS compliant. software that provides a graphical user interface (GUI) for control of the MAX17094s programmable features.
