    摘要: A wireless audio transmitter is capable of converting audio signals into wireless Bluetooth signals. The transmitter comprises an ADC converting input analog audio signals into digital signals. A CPU outputs original data complying with Bluetooth communication protocols. The original data are sequentially processed by a Bluetooth base band processor and a Bluetooth RF processor, and are converted into RF signals. Finally, the RF signals are transmitted in a wireless microwave manner by an antenna.

    摘要: A multiple-phase power converter comprises a non-isolated, double-ended transformer having a plurality of windings, a high-side switch portion, a low-side switch portion, an output portion, and a controller. The high-side switch portion includes a first power switch connecting an input voltage source (VIN) to a virtual phase node through a first winding of the plurality of windings and a second power switch connecting the input voltage source to the virtual phase node through a second winding of the plurality of windings. The first and second windings are arranged with opposite polarity. The low-side switch portion includes a third power switch connecting the virtual phase node to ground through a third winding of the plurality of windings and a fourth power switch connecting the virtual phase node to ground through a fourth winding of the plurality of windings. The third and fourth windings are arranged with opposite polarity. The output portion includes an output inductor connecting the virtual phase node to an output terminal providing an output voltage (VOUT). The controller is adapted to control operations of the first, second, third and fourth power switches such that the first and second power switches are enabled in respective alternating phases. The third switch is disabled when the second switch is enabled so that current flows concurrently through both the second and fourth windings to the output inductor during a first phase, and the fourth switch is disabled when the first switch is enabled so that current flows concurrently through the first and third windings to the output inductor.

    摘要: A light emitting diode (LED) driver circuit controls switching of an output transistor. The LED driver circuit monitors inductor current flowing through an output inductor that is coupled to one or more LEDs. In response to detecting that the inductor current has reached a peak value, the LED driver circuit switches OFF the output transistor. The LED driver circuit switches ON the output transistor in response to detecting zero crossing of the inductor current. The LED driver circuit may detect zero crossing of the inductor current from a gate voltage of the output transistor by detecting for a negative spike.
