The MAX15090 EV kit operates between MAX15090 EV kit 2.7V and 18V up to 12A load current capability. 12V, 12A DC power supply Evaluating the MAX15090A Voltmeter The MAX15090A EV kit can be used to evaluate the MAX15090A, with the MAX15090AEWI+ installed. The Procedure MAX15090A is pin-to-pin compatible with the MAX15090. The EV kit is fully assembled and tested. Follow the steps Refer to the MAX15090/MAX15090A IC data sheet for below to verify board operation. Caution: Do not turn on details on the MAX15090A. the power supply until all connections are completed. Circuit Breaker (CB) 1) Verify that a shunt is installed across pins 1-2 on jumper JU1. Jumper JU1 sets the current limit for the internal circuit breaker (CB) of the device. The CB pin can be connected 2) Turn on the power supply and set the supply to 12V, to a fixed resistor (R5) or a potentiometer (R11) to set the then disable the power supply. current limit. See Table 1 for shunt positions. 3) Connect the positive terminal of the power supply to The circuit-breaker threshold can be set according to the the IN banana jack on the EV kit. Connect the negative following formula: terminal of the power supply to the GND banana jack. I = R /3333.3 CB CB 4) Enable the power supply. where I is in A and R (the resistor between CB and CB CB 5) Verify that the voltage between the OUT and GND ground) is in . banana jacks is 12V. 6) Verify that the internal regul ator voltage (REG) is 3.3V.
