• Working Principle

  NCV8402STT1G works on the principle of PWM (pulse width modulation). The integrated switching regulator controller inside NCV8402STT1G senses the voltage on the DUT and sends the information to the dual transistor. The dual transistor then switches the current path of the DUT, controlling the current and voltage as per the needs.The current flowing through the gates of the dual transistor is reduced and the output current of the switch is increased. This makes NCV8402STT1G an efficient and reliable current control unit.
