1 MAX7 Evaluation Kit Evaluates: MAX7 MAX75 General Description The MAX7 evaluation kit (EV kit) evaluates the MAX7 MAX75 IC family of ultra-low quiescent current step-up DC-DC converters. The MAX7 EV kit features two independent circuits to evaluate two different IC packages of the MAX7 MAX75 family. Both circuits on the EV kit operate over an input range of 4mV to 5.5V, depending on load, with.88v typical startup with 3k load. Each circuit provides resistorconfigurable output voltages from.8v to 5V in mv/ step. Additionally, each circuit output on the EV kit delivers up to ma, 5mA, or 45mA of current, depending on the input voltage to the output voltage ratio. The EV kit comes with the MAX7ELT+ installed, while the MAX75ENT+ is a future product.

Detailed Description of Hardware The MAX7 EV kit evaluates the MAX7 MAX75 IC family of ultra-low quiescent current stepup DC-DC converters. The MAX7 EV kit features two independent circuits to evaluate two different IC packages of the MAX7 MAX75 family. Both circuits on the EV kit operate over an input range of 4mV to 5.5V. Each circuit provides resistor-configurable output voltages from.8v to 5V in mv/step. Additionally, each circuit output on the EV kit delivers up to ma, 5mA, or 45mA of current, depending on the input voltage to the output voltage ratio. The MAX7 circuit on the EV kit comes with the MAX7ELT+ (µdfn) installed, configured for a 3V output. The 3V output can deliver ma of current at.5v input.

2 MAX7 Evaluation Kit Evaluates: MAX7 MAX75 EN for the MAX75 Circuit The MAX75 circuit on the EV kit provides a set of jumpers (JU and JU) to configure the EN pin of the MAX75. Different settings of these two jumpers can simulate different pullup/pulldown scenarios at the EN pin. Refer to Table for JU and JU jumper settings. EN for the MAX7 Circuit The MAX7 circuit on the EV kit provides a set of jumpers (JU and JU) to configure the EN pin of the MAX7. Different settings of these two jumpers can simulate different pullup/pulldown scenarios at the EN pin. Refer to Table for JU and JU jumper settings. Table.

EN = (through pullup resistor R) Not Disabled. EN = (through -3 Installed pulldown resistor R) Not Installed Enabled. EN = high (through internal pullup) *Default position. Battery Holders The MAX7 EV kit provides battery holders for each of the two circuits. The battery holder V can accommodate a CR63 Lithium Coin cell to power the MAX75 circuit, while the V can hold an Energizer 364/363 silver oxide cell to power the MAX7 circuit. Spare Resistors and Inductors The EV kit provides spare resistors and inductors on the PCB s bottom side. The spare resistors can be used to reconfigure the EV kit to a different output voltage (V,.5V, 3V, or 3.3V). The spare inductors can be used to reconfigure the EV Kit output current ratings. Note that the (4 case size) inductors are used for evaluating the future MAX7. Table. EN on MAX7 (JU, JU) JU SHUNT POSITION Installed* Not Installed JU SHUNT POSITION Not Installed *Default position.
