Product Details

The MAX1606 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a step-up switching converter that generates a positive voltage to drive low-power LCD displays. The circuit is configured for a +18V output voltage and provides up to 20mA. Higher output voltages are possible by selecting different components.

The IC operates from a +2.4V to +5.5V supply voltage but can boost battery voltages as low as +0.8V up to +28V at the output. The IC also offers a true shutdown mode that disconnects the output from the input. Three different inductor current limits can be evaluated with the EV kit as configured.
