摘要： This disclosure relates generally to radio frequency (RF) switching converters and RF amplification devices that use RF switching converters. In one embodiment, an RF switching converter includes a switching circuit operable to receive a power source voltage, a switching controller configured to switch the switching circuit so that the switching circuit generates a pulsed output voltage from the power source voltage, and an RF filter configured to convert the pulsed output voltage into a supply voltage, wherein the RF filter includes a decoupling capacitor configured to receive the supply voltage. The switching controller is configured to generate a ripple correction current that is injected into the decoupling capacitor such that the decoupling capacitor filters the ripple correction current. The decoupling capacitor outputs the ripple correction current such that the ripple correction current reduces a ripple variation in a supply current level of a supply current resulting from the supply voltage.

摘要： A Switch Node Assisted Linear architecture, including a linear amplifier in parallel with a switched converter, is configurable in two tracking modes: (a) a SMAL regulator in which the amplifier sets load voltage with an envelope tracking bandwidth, and the switched converter is configured for current assist, and (b) a Switched Mode Power Supply configuration in which the amplifier is switch-decoupled, and the switcher circuit is switched configured with an output capacitor, operable as an SMPS providing load voltage with an adaptive tracking bandwidth that is less than the envelope tracking bandwidth. Staged switching effects substantially seamless transitions between tracking modes, with the amplifier holding the load voltage at a substantially constant envelope tracking voltage (CVET): (a) for ET-AT transitions, the CVET mode enables pre-charging the output capacitor to a target AT voltage, prior to switch-decoupling the amplifier; and (b) for AT-ET transitions, CVET mode enables discharging the output capacitor.

摘要： A primary side regulated isolation voltage converter. The primary side regulated isolation voltage converter comprises a control module and a ripple control circuit. The control module receives the voltage feedback signal and determines whether the isolation voltage converter operates in a light load state. When the isolation voltage converter operates in a light load state, the ripple control circuit senses the ripple of an output voltage signal to generate a ripple signal, and compare the ripple signal with a ripple threshold. When the ripple signal is larger than the ripple threshold, the isolation voltage converter jumps out the light load state.
