Publication number: 20240146316Abstract: A system performs a method of adaptive voltage scaling. The method includes generating a voltage adjustment signal based on a hint from a frequency-locked loop (FLL). The FLL includes an oscillator that generates a clock signal at a clock frequency. The voltage adjustment signal is sent to a power management unit (PMU) to cause the PMU to supply an adjusted operating voltage to the FLL. The method further includes updating a minimum code set according to the adjusted operating voltage and an operating temperature. The clock frequency of the oscillator is generated to match a target frequency according to the adjusted operating voltage and a code determined by the FLL from the minimum code set.Type: ApplicationFiled: October 19, 2023Publication date: May 2, 2024Inventors: Yu-Shu Chen, Hsin-Chen Chen, Kuan Hung Lin, Jeng-Yi Lin

Publication number: 20240128876Abstract: A switching control circuit for use in controlling a resonant flyback power converter generates a first driving signal and a second driving signal. The first driving signal is configured to turn on the first transistor to generate a first current to magnetize a transformer and charge a resonant capacitor. The transformer and charge a resonant capacitor are connected in series.
