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.
