This diagram depicts a complete 250 Watt Preregulator. At full load, this preregulator will exhibit a power factor of 0.99

at any power line voltage between 80 and 260 VRMS. This same circuit can be used at higher power levels with minor

modifications to the power stage. See Design Note 39B and Application Note U-134 for further details.
