REFACDC046 - Reference Design

Flyback Type PWM Mode Isolated 12V 1.4A 16.8W

This reference design uses BM2P13B1J.

  • This evaluation board outputs an isolated voltage of 12 V from an input of 90 Vac to 264 Vac, and the maximum output current is 1.4 A.
  • BM2P13B1J-Z which is PWM method DC/DC converter IC built-in 730 V MOSFET is used.
  • Built-in the low on resistor (1.0 Ω) and high voltage tolerant MOSFET (730 V) make designs easy.
  • PWM controller for AC / DC power supplies, the BM2P13B1J provides the optimum system for all products with outlets.
