This reference design provides four isolated outputs of 24 V,15 V, –15 V, 8 V and maximum 150-W output with two-switch flyback topology. The power supply can be powered from 350-V to 1500-V DC input. This design uses the valley switching UCC28740 flyback controller . The design achieves 89.11% efficiency at 600-V input and 86.17% efficiency at 1500-V input, full-load condition.
