摘要： A ripple detection unit detects a ripple current width of a motor current controlled according to PWM control. A ripple reference setting unit sets a reference value of the ripple current width. A frequency adjusting unit sets a control signal indicating a carrier frequency of the PWM control according to a ripple current width deviation. A carrier generation unit generates a carrier of the frequency based on the control signal. Thus, it is possible to realize feedback control of the carrier frequency for maintaining the ripple current width at an appropriate level.

摘要： Methods and apparatus for providing and controlling power to loads including one or more LEDs. In one example, a controlled predetermined power is provided to a load without requiring any feedback information from the load (i.e., without monitoring a load voltage and/or load current). In another example, a “feed-forward” power driver for an LED-based light source combines the functionality of a DC-DC converter and a light source controller, and is configured to control the intensity of light generated by the light source based on modulating the average power delivered to the light source in a given time period, without monitoring and/or regulating the voltage or current provided to the light source. In various examples, significantly streamlined circuits having fewer components, higher overall power efficiencies, and smaller space requirements are realized. Based on various power driver configurations, lighting apparatus incorporating one or more power drivers for one or more LED-based loads may be implemented, and multiple such lighting apparatus may be coupled together to form a lighting network in which operating power is efficiently provided throughout the network.

摘要： A DC-DC buck converter comprises a high-side power FET having a current path connected in series between an input terminal and an inductor connected to an output terminal supplying an output current to a load. The converter further comprises a low-side power FET having a current path connected between a reference terminal and an interconnection node of the high-side power FET with the inductor. The converter has a pulse width modulation controller receiving a feedback signal from the output terminal and providing pulse width modulated signals, and a gate driver circuit that receives the pulse width modulated signals from the pulse width modulation controller and applies pulse width modulated drive signals to the gates of the power FETs. The gate driver circuit supplies the drive signals to the gates of the power FETs at a variable voltage level adjusted in response to at least the output current, minimizing the power dissipation of the gate driver circuit.

摘要： A power device includes a transformer, a control signal outputting unit, and a power adjusting unit. The transformer has a primary coil and a secondary coil. The control signal outputting unit variably controls a parameter value and outputs, based on the parameter value, a control signal for controlling output power from the secondary coil. The power adjusting unit receives the control signal from the control signal outputting unit and adjusts power supplied to the primary coil based on the control signal. The power adjusting unit modifies a rate of change within a range in which the parameter value can be variably controlled, the rate of change being a rate of change in the power supplied to the primary coil with respect to the parameter value.

摘要： A power supply supplies an output current to an integrated circuit having at least one circuit block. The at least one circuit block has an operating mode controllable in response to an enable signal or a clock signal. The integrated circuit receives a load current to power the circuit block as a function of the operating mode of the circuit block. The load current is a portion of the output current. A receiver receives a weighted signal. The weighted signal is a function of the enable signal and the clock signal to indicate an expected load current of the integrated circuit. A controller controls the output current of the power supply as a function of the expected load current of the integrated circuit such that the power supply pre-emptively changes the output current.
