A 36W/12V DC/DC auxiliary power supply is designed based on the communication power supply standard. The circuit adopts the flyback toponology with RCD absorption circuit and it allows 40 to 60V voltage input. We select OB2269C with frequency shuffling function as the control chip which can reduce the loss with light load. The theoretical analysis of loss and the test results are given at the end.The two were found to be consistent.
