MAX1775

The MAX1775 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a dual step-down switching regulator circuit. 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 provides up to 500mA of current.

Power for the circuit can be provided from a +2.7V 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 MAX1775 EV kit demonstrates low quiescent current and high efficiency up to 95% for maximum battery life. Operation up to 1.25MHz allows the use of tiny surface- mount components.
