Flyback Type PWM Mode, Isolated 12V 1.0A 12W BM2P0363F Evaluation Board

This evaluation board output an isolated 12 V voltage, output from a 90 Vac to 264 Vac input. The maximum output power can output 12 W. BM2P0363F which is PWM method DC/DC converter IC built-in 650 V MOSFET is used. Low on-resistance 3.0 Ω 650 V MOSFET built-in contributes to high efficiency (86.7 % typ). PWM controller for AC / DC power supplies, the BM2P0363F provides the optimum system for all products with outlets.

  • Low noise (especially below 525kHz) due to 25kHz oscillation frequency
  • Input voltage 90V to 264V
  • Output voltage 12V±0.6V
  • Output current 0 to 1A
  • Efficiency 86.7% VIN=230V Io=1A
  • Substrate size 91mm x 55mm
