The NIS6201 charge pump is designed to provide economical, low level power to circuits above ground level potential, such as the drive for ORing diodes. It is a very cost-effective replacement for a small, isolated, switching power supply. It contains an internal linear regulator, and a versatile charge pump to allow bias voltage supplies to be transferred from a ground referenced source to a higher potential. The design of the charge pump allows for any isolation voltage required, as the high voltage components are external to the pump and can be sized accordingly.
