  • Control circuit for a switching regulator driving an LED load with controlled PWM dimming
    Patent number: 9774257
    Abstract: A switching regulator control circuit includes a circuit configured to generate a control signal to control conduction of the regulator switch in response to a reference signal that is ramped to control a rate of change of the regulated output of the regulator and the control signal is gated in response to a PWM signal.

  • Anti-snapback circuitry for metal oxide semiconductor (MOS) transistor
    Patent number: 9269705
    Abstract: A circuit for protecting a metal oxide semiconductor (MOS) device is configured to hold down or pull down a voltage at a gate of the protected MOS device during an electrostatic discharge (ESD) event. The circuit includes at least one active device or capacitance-providing element connected to the gate of the protected MOS device, configured to pull down or hold down the voltage at the gate of the protected MOS device when the ESD event occurs.

  • SIMPLIFIED CONTROL OF COLOR TEMPERATURE FOR GENERAL PURPOSE LIGHTING
    Publication number: 20110115407
    Abstract: A lighting system includes at least first and second light sources providing first and second colors of light. Control circuitry is operatively coupled to the first and second light sources, and is configured to control the first and second light sources relative to one another to provide a color point that is linearly controlled to approximate a non-linear target lighting behavior in the CIE 1931 color space.

  • System and method for dynamic ESD Protection
    Patent number: 6898061
    Abstract: A system and method for dynamically protecting a vulnerable device from an ESD event includes an ESD event sensor and a breakdown voltage adjustment circuit. The ESD event sensor detects an ESD event and provides a signal to the breakdown voltage adjustment circuit indicating that an ESD event has occurred. The breakdown voltage adjustment circuit receives the signal from the ESD event sensor and adjusts the breakdown voltage of the vulnerable device during the ESD event.
