Evaluates: MAX17010 19-0855 Rev 0 7/07 MAX17010 Evaluation Kit General Description Features The MAX17010 evaluation kit (EV kit) is a fully assem- 1.8V to 5.5V Input Range bled and tested surface-mount printed circuit board Output Voltages (PCB) that provides the voltages and features required 8.5V Output at 300mA from a 2.7V Input (Step- for active-matrix, thin-film transistor (TFT), liquid-crystal Up Switching Regulator) displays (LCDs). The EV kit contains a step-up switch- ing regulator, a high-speed operational amplifier (op 23V Output at 20mA (Positive Charge Pump) amp), and eight high-voltage level-shifting buffers for -7.5V Output at 20mA (Negative Charge Pump) scan-driver applications. 4.25V High-Current Op Amp Output The EV kit operates from a DC supply voltage of 1.8V to Resistor-Adjustable Switching-Regulator and Op 5.5V. The step-up switching regulator is configured for a Amp Output Voltage 8.5V output providing at least 300mA from a 2.7V input. The positive charge pump is configured for a 23V output Eight 30V to -10V High-Voltage Level-Shifting providing at least 20mA. The negative charge pump is Buffers configured for a -7.5V output providing at least 20mA. Greater than 85% Efficiency (Step-Up Switching The op amp is configured for 4.25V, capable of provid- Regulator) ing up to 150mA peak. The high-voltage, level-shifting scan driver buffers eight logic inputs and shifts them to 1.2MHz Step-Up Switching Frequency a desired level to drive TFT-LCD row logic. 1.2mm Low-Profile Surface-Mount Components The MAX17010 EV kit demonstrates low quiescent cur- Fully Assembled and Tested rent and high efficiency (> 85%) for maximum battery life.
