REFACDC044 - Reference Design

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.
