REFACDC030

REFACDC030 - Reference Design

Isolated Flyback Type PWM Mode 48W 24V Output

This reference design uses BM1P10CFJ.

  • 1. Standby mode significantly reduces standby power consumption.
  • 2. Spacing-saving is realized by MOSFET, start circuit incorporation.
  • 3. It realizes the high flexibility because current sense resistance adjustment is possible.
  • 4. Voltage = 45V or less one second after the cutting are realized by X condenser electric discharge function incorporation.
  • 5. Electricity is reduced at no load time by power save function incorporation.
  • 6. Efficiency in the light load is improved largely by burst movement, a frequency reduction mode.
