  • Secondary side controller and method therefor
    Patent number: 7515442
    Abstract: In one embodiment, a secondary side power supply controller is configured to enable a secondary side power switch independently of a state of a drive signal used to control a primary side of the power supply.

  • Switching power supply with reduced energy transfer during a fault condition
    Patent number: 6385060
    Abstract: A switching regulator (18) for use in a switching power supply (10) detects a fault condition by looking for presence of feedback signals during a timer period. If feedback is present but less than a threshold value during the timer period, then the switching power supply (10) is operating normally. If feedback is not present during the timer period, then the switching power supply is in a fault condition. One way of implementing the timer is to charge and discharge by-pass capacitor (23). The timer period is the time for the VCC voltage to drop from a maximum value to a predetermined threshold. When a fault is detected, the gate drive signal from the switching regulator is disabled for a period of time before attempting auto-restart.

  • Circuit with hysteresis and method using same
    Patent number: 5952870
    Abstract: An apparatus and method is provided with hysteresis for switching a load according to an input signal. There is a transfer gate for transferring a first signal to a second signal. A controller receives the first signal and the second signal and provides a control signal for the transfer gate. The control signal enables the transfer gate if the first signal reaches a first magnitude and disables the transfer gate if the first signal reaches a second magnitude. The control signal is obtained from a voltage divider across the first signal. A portion of the voltage divider is shorted out by a switch activated by a second signal. Thus, the control signal depends on the second signal. The apparatus is entirely powered by the second signal.
