App note: SEPIC-Ćuk Converter gives split rails from a single supply

Posted on Sunday, September 9th, 2012 in app notes by DP

Analog Devices describes the SEPIC-Ćuk Converter. This type of DC/DC converter is used to create two outputs with the same voltage, but different polarities. This is particularly useful for powering the two rails of op-amp based circuits.

A better solution is a SEPIC-Ćuk converter. This topology consists of an unregulated Ćuk converter tied to the same switching node as a regulated SEPIC converter. This combination results in two supplies that track each other very well under all but a 100% load mismatch.
