This reference design uses a single UCC25800-Q1 to drive two LLC transformers with 600-kHz switching frequency. The transformer used in this design is 750319177 which is an off-the-shelf catalog transformer featuring low-interwinding capacitance of 0.68-pF typical which is beneficial for minimizing common-mode current in gate driver bias applications with high slew rates. This design generates two isolated 18-V rails. Each output can be loaded to 1.5 W.
