This reference design generates two isolated +12-V rails at 100 mA each from a 12-VDC input voltage. The design is for a small footprint by using a primary resonant LLC topology with a single driver and transformer with reinforced insulation. This design can be used for an application where bias power is needed across a high-voltage isolation barrier.
