摘要： The present invention is a switching power supply that switches (dithers) between at least two switching frequencies without introducing a ripple signal at the dithering frequency, which is based on the time duration of a dithering cycle. In one embodiment of the present invention, an average current in an energy transfer element, such as an inductive element, during operation using one switching frequency is regulated to be approximately equal to the average current during operation using any other switching frequency. The average current may be regulated by controlling the durations of transition periods between operating using one switching frequency and operating using another switching frequency. By maintaining a constant average current while operating using different switching frequencies, dithering frequency ripple may be significantly reduced or eliminated.

摘要： An apparatus and corresponding method are provided for regulating the voltage potential of a lithium ion battery based upon an operating range having an upper threshold (e.g., on the order of 4.2 v) and a lower threshold (e.g., on the order of 2.5 v) and for providing a reduction in dissipated power when the lithium ion battery is charging and when a load is drawing upon the lithium ion battery. The apparatus includes a p-minus substrate and a first p-channel enhancement Field Effect Transistor (FET) integrally formed on the p-minus substrate. The first p-channel enhancement FET is configured to limit charging of the lithium ion battery when the voltage potential of the lithium ion battery is greater than the upper threshold. A second p-channel enhancement FET is integrally formed on the p-minus substrate and connected in parallel with the first p-channel enhancement FET and configured to limit discharging of the lithium ion battery when the voltage potential of the lithium ion battery is less than the lower threshold. A third p-channel enhancement FET is integrally formed on the p-minus substrate and connected in parallel with the first p-channel enhancement FET and the second p-channel enhancement FET. The third p-channel enhancement FET encompasses a substantially larger area of the p-minus substrate as compared to each of the first p-channel enhancement FET and the second p-channel enhancement FET such that a substantially reduced resistive path is presented by the third p-channel enhancement FET relative to the resistive paths associated with the first and second p-channel enhancement FETs. The reduced resistive path provides reduced dissipated power while the lithium ion battery is charging and when the load is drawing upon the battery in the operating range.

摘要： The present disclosure relates to a flexible direct current (DC)-DC converter, which includes a charge pump buck power supply and a buck power supply. The charge pump buck power supply and the buck power supply are voltage compatible with one another at respective output inductance nodes to provide flexibility. In one embodiment of the DC-DC converter, capacitances at the output inductance nodes are at least partially isolated from one another by using at least an isolating inductive element between the output inductance nodes to increase efficiency. In an alternate embodiment of the DC-DC converter, the output inductance nodes are coupled to one another, such that the charge pump buck power supply and the buck power supply share a first inductive element, thereby eliminating the isolating inductive element, which reduces size and cost but may also reduce efficiency.

摘要： RF PA circuitry and a DC-DC converter, which includes an RF PA envelope power supply and DC-DC control circuitry, are disclosed. The PA envelope power supply provides an envelope power supply signal to the RF PA circuitry. The DC-DC control circuitry has a DC-DC look-up table (LUT) structure, which has at least a first DC-DC LUT. The DC-DC control circuitry uses DC-DC LUT index information as an index to the DC-DC LUT structure to obtain DC-DC converter operational control parameters. The DC-DC control circuitry then configures the PA envelope power supply using the DC-DC converter operational control parameters. Using the DC-DC LUT structure provides flexibility in configuring the DC-DC converter for different applications, for multiple static operating conditions, for multiple dynamic operating conditions, or any combination thereof.

摘要： A charge pump of a PA bias power supply, PA bias circuitry, and a process to optimize efficiency of the PA bias power supply are disclosed. The charge pump operates in one of multiple bias supply pump operating modes, which include at least a bias supply pump-up operating mode and a bias supply bypass operating mode. The process prevents selection of the bias supply bypass operating mode unless a DC power supply voltage is adequate to allow the PA bias circuitry to provide minimum output regulation voltage at a specified current. Otherwise, the bias supply pump-up operating mode is selected. The charge pump operates more efficiently in the bias supply bypass operating mode than in the bias supply pump-up operating mode; therefore, selection of the bias supply bypass operating mode, when possible, increases efficiency.

摘要： A sample-and-hold (SAH) current estimating circuit and a first switching power supply are disclosed. The first switching power supply provides a first switching power supply output signal based on a series switching element and a setpoint. The SAH current estimating circuit samples a voltage across the series switching element of the first switching power supply during an ON state of the series switching element and during a ramping signal peak to provide an SAH output signal based on an estimate of an output current of the first switching power supply output signal. The first switching power supply selects the ON state of the series switching element, such that during the ramping signal peak, the series switching element has a series current having a magnitude, which is about equal to a magnitude of the output current of the first switching power supply output signal.

摘要： A direct current (DC)-DC converter having a DC-DC converter semiconductor die and an alpha flying capacitive element is disclosed. The DC-DC converter semiconductor die includes a first series alpha switching element, a second series alpha switching element, a first alpha flying capacitor connection node, which is about over the second series alpha switching element, and a second alpha flying capacitor connection node, which is about over the first series alpha switching element. The alpha flying capacitive element is electrically coupled between the first alpha flying capacitor connection node and the second alpha flying capacitor connection node. By locating the first alpha flying capacitor connection node and the second alpha flying capacitor connection node about over the second series alpha switching element and the first series alpha switching element, respectively, lengths of transient current paths may be minimized, thereby reducing noise and potential interference.

摘要： At least a first shunt switching element and switching control circuitry of a first switching power supply are disclosed. At least the first shunt switching element is coupled between a ground and an output inductance node of the first switching power supply. The first switching power supply provides a buck output signal from the output inductance node. The switching control circuitry selects one of an ON state and an OFF state of the first shunt switching element. When the buck output signal is above a first threshold, the switching control circuitry is inhibited from selecting the ON state. The first switching power supply provides a first switching power supply output signal based on the buck output signal. By using feedback based on the buck output signal, the switching control circuitry may refine the timing of switching between series switching elements and shunt switching elements to increase efficiency.
