A MOSFET with high withstand voltage and low on-resistance is suitable for the power module. By keeping the on-resistance low, heat generation and current consumption can be minimized, and loss can also be reduced. Toshiba's Power MOSFET Series uses high heat dissipation packages to further reduce heat generation. The transistor output photocoupler is used for voltage feedback to the primary side in the power supply module circuit. Signal transmission at different potentials is required on the primary and secondary sides, and signal path isolation can be easily and reliably realized by using an optical coupling method photocoupler. When using photocouplers, it is essential to observe the safety standards established in each country. Toshiba Photocouplers have been approved by UL1577, VDEs: EN60747-5-5, EN62368-1, and others.

Toshiba has provided the Switched Mode Power Supply Library to support power supply designs such as DC-DC power supply. In addition, the Reference Design Center publishes examples of the design of various power supply circuits, providing design ideas for high efficiency in various power supply circuits. Both of them can be used free of charge, so please use them as a help in designing the power supply.
Toshiba offers super-junction MOSFET series suitable for high-output power supply applications and D-MOS (double-diffused) MOSFET series suitable for low-output power supply applications.
Toshiba's portfolio of isolators/solid state relays includes photocouplers, solid-state relays and fiber-optic transmission modules. Toshiba's photocouplers help improve the safety, cut the power consumption and reduce the size of end products.
