refacdc044reference design / application evaluation kit | rohm co., ltd.-凯发k8一触即发
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.
