摘要： An integrated circuit controls a power converter that includes single stage buck-boost converter and a switching full bridge that may be used to drive an HID lamp. The single stage buck-boost converter reduces the complexity and parts count of the power converter, or electronic ballast, while permitting PFC and DC bus voltage regulation under control of the integrated circuit to maintain constant power on the HID lamp. The integrated circuit simplifies the design of power converters and electronic ballasts in particular, while reducing part count, complexity and cost in conjunction with the single stage buck-boost converter and the full bridge switching circuit.

摘要： An electronic ballast provides fault detection and safety features for overcurrent protection and hard switching at a half bridge. A voltage controlled oscillator supplies a switching frequency that is modifiable based on operationalfeedback parameters. A feedback circuit senses load current and output voltage to determiner fault conditions and to provide control information for adaptively adjusting the frequency of the voltage controlled oscillator. By appropriately controlling the voltage controlled oscillator output, the electronic ballast maintains a zero volt switching with minimum current switching to achieve an efficient and robust electronic ballast control. The entire control is integrated on a single integrated circuit.

摘要： A high voltage offset detection circuit registers the voltage at the midpoint of a switching half-bridge and may determine when the midpoint voltage reaches a given value to avoid hard-switching in the half-bridge switches. The midpoint voltage of the switching half-bridge is applied through a buffer to a MOSFET that is current limited to produce a voltage that reflects the voltage of the midpoint of the switching half-bridge. The voltage produced by the MOSFET may be supplied to a comparator with a threshold input to obtain a signal that indicates when the switches of the switching half-bridge may be turned on to avoid hard-switching. An adaptive dead-time circuit and method may comprise the above sensing circuit, a first circuit for generating a first signal indicative of a high to low transition of the midpoint voltage; and an output circuit for generating an adaptive dead-time output signal based thereon. A second circuit may generate a second signal indicative of a low to high transition of the voltage; wherein the output circuit generates the adaptive dead-time output signal based on both the first and second signals. The second circuit preferably generates the second signal by reproducing the first signal. The first circuit may generate the first signal by charging a capacitor in response to pulses, and the second circuit may generate the second signal by charging a second capacitor corresponding to said first capacitor, and the adaptive dead-time output signal may be responsive to the charges on the first and second capacitors.

摘要： A bootstrap diode emulator circuit for use in a half-bridge switching circuit employing transistors connected to one another in a totem pole configuration, a driver circuit for driving the transistors, and a bootstrap capacitor for providing power to the high-side driver circuit. The bootstrap diode emulator circuit includes an LDMOS transistor having a gate, a back-gate, a source and a drain, the drain of the LDMOS transistor being coupled to the high-side supply node, the source of the LDMOS transistor being coupled to the low-side supply node; a gate control circuit electrically coupled to the gate of the LDMOS transistor, and a dynamic back-gate biasing circuit electrically coupled to the back-gate of the LDMOS transistor. The dynamic back-gate biasing circuit is operable to dynamically bias the back-gate of the LDMOS transistor when the LDMOS is turned on by applying a voltage to the back-gate of the LDMOS transistor that is close to but slightly lower than a voltage of the drain of the LDMOS transistor.

摘要： The fault latch and filter circuit used in a MOSgated driver for a high side power MOSgated device to turn off the MOSgated device high side output in response to a given fault condition is located in the high side of the circuit and in a floating well of a semiconductor chip containing the driver circuit. The fault latch and filter are connected to the output driver circuit through a gate which also receives the high side filter and latch which are operated by the input control logic circuits through a level-shift up circuit. The fault latch circuit has an output which is level-shifted down by a single PMOS device to a fault reporting latch circuit on the low side of the device.
