This reference design provides two isolated voltages (6 V at 200 mA: 12 V at 200 mA) from a DC-input supply (10 V - 30 V). By means of zero ohm resistors: a flexible transformer can be configured to change the turns ratio and output voltages without any layout change. The converter enables an isolated DC/DC solution with high density and low component count. No auxiliary transformer winding is required and a 100-V rated primary-side switch is integrated.
