The PMP30280 reference design generates two isolated outputs (6V @ 1.2A / 20V @ 0.15A) from an AC input (48VAC to 240VAC). The LM5021 operates at either a fixed switching frequency or in a skip cycle mode when the converter load is light. The design uses an optical coupler to regulate the output and to improve transient response.
