By MAX15032 EV kit default, the EV kit is configured to operate with a 2.9V to 5.5V input voltage range. To operate the EV kit in 2.9V to 5.5V, 100mA DC power supply (VIN) the 5.5V to 11V input range, the following configuration Voltmeter changes should be made: Procedure Remove capacitor C5 (0.01FF). The EV kit is fully assembled and tested. Follow the Connect the CP pin (U1, pin 7) to VIN. steps below to verify board operation. Caution: Do not turn on the power supply until all connections are Leave the CN pin (U1, pin 6) unconnected. completed.
