REFACDC032 - Reference Design

Flyback Type PWM Mode Isolated 24V 1.67A 40W

This evaluation board outputs an isolated voltage of 24V from an input of 90Vac to 264Vac,and the maximum output current is 1.67A. BM2P060MF which is PWM method DC/DC converter IC built-in 650V MOSFET is used.

  • Low on-resistance 0.7Ω 650V MOSFET built-in contributes to high efficiency(91%).
  • PWM controller for AC/DC power supplies,the BM2P060MF provides the optimum system for all products with outlets.
