Abstract: An electronic component for providing optical isolation an electronic component package, a phototriac disposed within the electronic component package for providing the optical isolation, and a reverse zero-cross feedback channel integrated into the electronic component package to thereby provide zero-cross detection. The electronic component may be in a circuit which includes a phase control circuit. A method of driving an AC load and providing zero-cross detection using a single electronic component includes providing an electronic component having an electronic component package, a phototriac disposed within the electronic component package, and a reverse zero-cross feedback channel integrated into the electronic component package to thereby provide for zero-cross detection. The method further includes placing the electronic component within a circuit.

Abstract: An LED driver drives one or more strings of series-connected LEDs. A feedback voltage at a sense resistor is detected by an op amp, and the op amp controls the conductivity of a MOSFET in series with the LEDs to regulate the peak current. The MOSFET is also controlled by a PWM brightness control signal to turn the LEDs on and off at the PWM duty cycle. A boost regulator provides an output voltage to the string of LEDs. A divided voltage at the end of the string of LEDs is regulated by the boost controller to keep the divided voltage constant. When an LED becomes an open circuit, the boost regulator controller is immediately decoupled from the regulator's switching transistor. If an LED shorts, the boost regulator reduces its output voltage, and the duty cycle of the brightness control signal is automatically increased.

Abstract: Two independent control variables, i.e. the frequency and the duty cycle of the driving waveform to an output driver, can be used to optimize the operation of a cold cathode fluorescent lamp (CCFL). The frequency of the driving waveform can be used to control the gain of a piezoelectric transformer (PZT) in a CCFL circuit. In contrast, the duty cycle of the driving waveform can be used to control the amplitude of the sinusoidal waveform at the PZT input terminal, and thus the current through the CCFL.
