The MAX1774 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a dual step-down switching converter with a backup converter circuit and low-voltage detectors. The circuit is configured for a main output voltage of 3.3V and a core output voltage of 1.8V. The main output provides up to 1.5A, and the core output provides up to 500mA of current. Power for the circuit can be provided from a 3.65V to 5.5V DC source. The EV kit can be reconfigured for input voltages up to 28V. The core's input can be powered from the input source, or for higher input voltages, from the main output. The EV kit circuit includes battery monitoring, switchover, and backup, allowing automatic backup operation.
