Power Supply Circuit Diagram
Power MOSFETs
A MOSFET with high withstand voltage and low on-resistance is suitable for the PFC circuit of a DC-DC power supply. Heat generation and current consumption can be kept to a minimum by keeping on-resistance low. Reducing the output charge can also reduce output loss. Toshiba's U-MOS IX Series power MOSFETs use high heat dissipation packages to further minimize heat generation.
Photocouplers
Transistor-output photocouplers are commonly used for voltage feedback to the primary DC-DC supply. Signal transmission over different potentials is required on the primary and secondary sides, and electrically isolated photocouplers are a simple way to ensure isolation. An IC output photocoupler that can communicate at high speed for signal communication in the power supply circuit is also recommended.
Additionally, it's important to comply with safety standards established in each country. Toshiba photocouplers help with this process as these devices are approved for UL 1577 VDE: EN 60747-5-5, EN 62368-1, and others.

Power line-protection
Due to hot-swapping requirements, Toshiba's current eFuse IC is beneficial for 12V and 5V power line protection in server designs. eFuses are effective at protecting equipment from surges such as overvoltage and overcurrent. This family features protective functions such as short-circuit, overcurrent, overvoltage, and inrush current suppression in a single package. These features help improve overall protection and offer IEC 62368-1 to help qualify complete designs. In addition, high IPP ESD protection diodes and SBDs can be combined to provide a robust protection circuit.
