Switched mode power supply with adaptive clock frequency control
A recently granted patent (Publication Number: US12003178B2) discloses a novel switched mode power supply (SMPS) system that includes an input node, an output node, switches, an inductor, an error amplifier, an oscillator circuit, an adaptive minimum duty-cycle circuit, and a pulse-width modulation (PWM) circuit. The system is designed to efficiently regulate the output voltage by adjusting the oscillating frequency of the clock signal in response to the error voltage signal. The adaptive minimum duty-cycle circuit plays a crucial role in this process by generating a current signal to vary the oscillating frequency, ensuring optimal performance of the SMPS.
Furthermore, the patent also covers a controller for the SMPS, which includes an error amplifier, an oscillator circuit, an adaptive minimum duty-cycle circuit, and a PWM switching control circuit. This controller is responsible for monitoring the output voltage, generating the clock signal, adjusting the oscillating frequency, and providing the necessary PWM switching control signal to regulate the power switches effectively. The adaptive minimum duty-cycle circuit within the controller ensures that the system operates efficiently by dynamically adjusting the oscillating frequency based on the error voltage signal. Overall, the patented technology aims to enhance the performance and efficiency of SMPS systems by incorporating innovative control mechanisms and adaptive circuits to optimize power regulation processes.
