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.
