quasi-resonant method isolated 90w 20v 4.5a

this reference design uses bm1q104fj.

  • this evaluation board outputs an isolated voltage of 20 v from an input of 90 vac to 264 vac, and the maximum output current is 4.5 a.
  • the bm1q104fj, the qr controller for ac/dc power supplies, provides the optimal system for all products where an outlet is present.
