摘要： A Buck switching regulator includes first Buck switching regulator circuitry is operable to generate a first output voltage from an input voltage and operable to generate a first sensed voltage having a value that is proportional to an output current being provided by the first Buck switching regulator circuitry. The first Buck switching regulator circuitry receives an input current and operates at a first duty cycle determined by a duty cycle signal. Input current sensing circuitry includes second Buck switching regulator circuitry coupled to the first Buck regulator switching circuitry to receive the duty cycle signal and to receive the first sensed voltage as an input voltage to the second Buck switching regulator circuitry. The second Buck switching regulator circuitry is operable responsive to the duty cycle signal to generate a second output voltage from the first sensed voltage.

摘要： A power supply includes a main power supply section having power dissipating components therein and a stand-by power supply section. When the main power supply section is off, the stand-by power supply section uses the power dissipating components in the main power supply section to dissipate waste power. When the main power supply section is on, power from a secondary power supply driven by the output from the main power supply section is used to drive the stand-by power supply section thereby reducing any power dissipating requirements of the stand-by power supply section.

摘要： A double-ended, DC-AC converter supplies AC power to a load, such as a cold cathode fluorescent lamp used to back-light a liquid crystal display. First and second converter stages generate respective first and second sinusoidal voltages having the same frequency and amplitude, but having a controlled phase difference therebetween. By employing a voltage controlled delay circuit to control the phase difference between the first and second sinusoidal voltages, the converter is able to vary the amplitude of the composite voltage differential produced across the opposite ends of the load. The converter may be either voltage fed or current fed.

摘要： An apparatus and method for controlling the operation of a utility device, such as a cold cathode fluorescent lamp that is powered in accordance with a pulse width modulation (PWM) signal, includes an analog sensor which monitors the utility device to derive an output signal representative of the PWM signal. An integrating analog-to-digital converter (ADC), which is coupled to the sensor and has its operation synchronized with an integral multiple of the period of the PWM signal, produces an output representative of an average of the output of the utility device.
