MAX14750EVKIT#

MAX14750 Evaluation Kit General Description The MAX14750 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX14720/MAX14750 power-management solutions with I2C capability for space-constrained, battery-powered applications. Both the MAX14720 and MAX14750 integrate a synchronous buck converter, a buck-boost converter, a linear regulator, and a power switch. The MAX14750 provides individual pin enables for each function, while the MAX14720 includes a push-button monitor and sequencing controller. Refer to the MAX14720/MAX14750 IC data sheet for detailed information regarding the operation and features of the devices. The EV kit comes standard with the MAX14750A installed, but can also be used to evaluate the MAX14720 by replacing the MAX14750A (U1) with the MAX14720. Request a free sample of the MAX14720 when ordering the EV kit. Evaluates: MAX14720/MAX14750 Detailed Description of Hardware The MAX14750 evaluation kit (EV Kit) evaluates the MAX14720/MAX14750 compact power management solutions. See Table 1 thru Table 3 for pin description of the three connectors J1–J3. Hardware Modification Resistors R1 and R4–R9 are uninstalled by default. VCC can be used to power the inputs of the four major blocks (LIN, BIN, HVIN, and SWIN) by populating R1, R5, R7, and R9 accordingly. The blocks can also be cascaded in any order by selectively populating R4, R6, R7, and R9. The EV kit hardware is configured by default for the evaluation of the MAX14750. To evaluate the MAX14720, remove R2 and install a short at R3. Features ●● RoHS Compliant ●● Proven PCB Layout ●● Full Assembled and Tested ●● I2C Serial Interface 19-8661; Rev 0; 10/16 Ordering Information appears at end of data sheet. MAX14750 Evaluation Kit Table 1.
