  • Board mountable power supply module with multi-function control pin
    Patent number: 6437547
    Abstract: A board mountable power supply module is described. The power supply module includes a power train for converting an input voltage into a regulated output voltage and a controller operable to control the power train. The power train is connected to the input and output voltages through an input voltage pin, an output voltage pin and a common pin. The controller includes a multifunction control pin, which allows for disabling the power supply module and for trimming the output voltage. Additionally, two or more power supply modules can be connected in parallel to form a power supply that is capable of meeting increased load current requirements. Each of the multifunction control pins in the power supply is electrically connected together to improve current sharing between modules by reducing internal variances between modules.

  • Circuit for controlling the switching times of inverting switching devices
    Patent number: 3965374
    Abstract: Disclosed is a circuit for controlling the switching duration of inverting switching devices. The circuit comprises a capacitor connected to the output of the controlled switching device, a resistor connected between the capacitor and a common terminal, and a double Zener diode connected between the switching device's input and the capacitor-resistor junction.
