ABSTRACT:
The driver is a controlled four-terminal device having an extremely high switching speed, small input current and large output current capability. The driver can control switching power devices such as MOSFETs, thyristors and triacs, requiring floating drive circuit and large input current pulses. The driver is intended to operate in systems requiring a constant or occasional switching, e.g. switching power supplies and switching power amplifiers. One driver comprises a source providing a current in response to input signal, a resistor obtaining a voltage in response to the current, a capacitor storing a supply voltage, a rectifier coupled between the capacitor and resistor for limiting the voltage thereacross, and a buffer receiving the supply voltage and providing binary output signal in response to the voltage across the resistor.
