The Landscape of Isolated DC/DC Bias Power Supplies - issue 2/2020 June, 16 2020
Moving signals and power across an isolation barrier is a common challenge for designers. Isolation might be required for safety, noise immunity or large potential differences between system domains. Understanding system-level specifications like the number of outputs, regulation requirements, output power, insulation rating, operating temperature and input voltage range are critical. From there, designers can derive the lowest-cost solution that meets all of the system requirements..

Inverting Buck Regulator Saves Space and Power - issue 7/2011 January, 26 2012
Designers are periodically faced with the requirement to generate a negative voltage rail in order to provide a bias voltage for applications using sensors which read signals both above and below ground. For many engineers, the first thought will be to use inverting regulated charge pumps: in fact, these are ideal for handheld applications where the output voltage required is less than -5V and the input is typically a lithiumion battery.
