Generating a supply rail for the MC34940 and MC33941 in low-voltage systems

This application note demonstrates how to generate the supply voltage required by Freescale's MC34940 and MC33941 Electric Field Imaging Devices in low-voltage systems that do not have an appropriate voltage available. Inductive boost and regulated charge pump techniques are compared and example circuits are given using off-the-shelf components.
