refacdc030reference design / application evaluation kit | rohm co., ltd.-ag凯发旗舰厅
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.
