The voltage error signal is a difference between a reference voltage and the output voltage. The controller comprises a synchronizer to generate a first clock signal for clocking a low frequency domain of the controller, and a digital PWM controller clocked by the first clock signal and configured to determine an on-time information of the PWM signal and a PWM generator to generate the PWM signal based on the on-time information. The synchronizer is configured to synchronize a frequency of the PWM signal to a frequency imposed by the external reference signal by synchronizing a frequency of the first clock signal to the frequency imposed by the external reference signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switched power converter with improved synchronization of a pulse width modulation switching frequency","description":"Power converter includes a switched power stage to generate an output voltage from an input voltage, and a controller to generate a pulse width modulation (PWM) signal for switching the switched power","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9729045","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
