Abstract: A driver circuit for delivering a generally constant voltage to a load is disclosed. The driver circuit includes a source of incoming AC power, a rectifier, and a constant voltage driver. The rectifier is connected to the source of incoming AC power and produces a DC voltage. The constant voltage driver receives the DC voltage from the rectifier. The constant voltage driver includes a selectively activated switching element for receiving the DC voltage, a controller, and an output line. The controller receives the DC voltage and is configured to send a drive signal to the switching element in order to activate the switching element. The output line provides the generally constant voltage to the load.

Abstract: A PWM control unit is provided. A comparison unit compares an output voltage with a reference voltage to generate a first compared result, and controls a voltage of a first node. A constant current source is coupled to the first node. A storage module is coupled to the first node and receives a ground voltage. A first comparator compares the output voltage with the voltage of the first node to generate a turn-on signal. A second comparator compares the voltage of the first node with the input voltage to generate an output signal. A logic gate generates a turn-off signal according to the turn-on and output signals. When each of the turn-on and output signals is at a first level, a logic gate asserts the turn-off signal at a second level. The PWM generator combines the turn-on and turn-off signals to generate a PWM signal.

Abstract: A switched mode assisted linear regulator includes a linear amplifier (LA) and a buck converter configured as a current source. In example embodiments, the buck converter circuit includes a power switch M1 with an M1 body diode (tub), and includes buck turn-off circuitry configured to avoid negative inductor current by controlled switching of the tub to the higher of VIN and a second voltage. For DC-coupled configurations, boost functionality is provided by an LA boost supply, and the tub is switched to the boost supply. For AC-coupled configurations, boost functionality can be provided without boosting the LA supply rail by constraining signal peak-to-peak amplitude to be less than the LA supply voltage (maintaining a DC-average voltage on the AC-coupling capacitor), and the tub is switched to the higher of VIN and VOUT. The buck turn-off circuitry can include zero crossing detection to control M1 tub switches.
