MOSFET Selection of Load Switch

Load switch is Typical applications of the MOSFET. It is used in electronic devices of a wide range of fields, such as portable equipment and AV equipment and industrial equipment market. This program allows you to quickly selecting the best MOSFET.

This tool calculates the resistance from the voltage difference between the input voltage and the output voltage (drop-down voltage) and the output current (the current flowing through the MOSFET).
Calculation tool will search for the appropriate on-resistance MOSFET.It does not guarantee the operation.
Please use the product after you consider whether enough.

  • Input voltage (Vin)[Q1]:Please input the minimum voltage in your product. (1.5V≦Vin[Q1]≦30V)
  • Output voltage (Vout)[Q1]:Please input the target voltage in your product.
  • Q1 Drive Voltage (Vcont)[Q1]:Please input the drive voltage for MOSFET[Q1] when MOSFET[Q1] is Nch.
    (Q1 Drive Voltage (Vcont)[Q1] <= Vout+20V, Voltage is based on GND)
  • Q2 Drive Voltage (VGS2)[Q2]:Please input a voltage less than or equal to 10.)
    (VGS2[Q2]<=10V,Voltage is based on GND)
