REFACDC001

REFACDC001 - Reference Design

Non-Isolated PWM type Buck Convertor 8W 20V Output

non-isolated from inputs from 90 Vac to 264 Vac, with an output maximum current of 0.4A It was developed mainlu for power supplie for IH cookers and IH cookers. The non-insulated output can be used as a power supply for control of inverters,etc. A PWM controller for AC/DC power supplies,the BM2PAB1Y provides the ideal system for small appliances with outlets.

  • Half-wave rectified input
  • Simple noise filter
  • High efficiecny (85.3% typ)
