Samsung patents voltage regulator design for electronic devices
Samsung has filed a patent for a specific type of power management circuit called a buck converter, which steps down high voltage to lower levels needed by chips. The design uses a combination of an integrator and an adder circuit to adjust the power signal based on voltage feedback, aiming for stable output.
In the filing’s own words
A buck converter generating an output voltage by stepping down an input voltage is provided. The buck converter includes an output circuit including an inductor and a switch controller configured to control a current of the inductor based on a pulse width modulation signal, a comparator configured to output an error voltage based on a reference voltage and a feedback voltage, an integrator circuit configured to receive a sensing voltage generated at an end of the inductor and outputting an integral output based on the sensing voltage, an adder circuit configured to receive the error voltage and outputting an addition output based on the error voltage, the feedback voltage, and the reference voltage, and a controller configured to output the pulse width modulation signal by comparing the integral output with the addition output.
What exactly they claim (claim 1)
1. A buck converter comprising: an output circuit including an inductor and a switch controller configured to control a current of the inductor based on a pulse width modulation signal; a comparator configured to output an error voltage based on a reference voltage and a feedback voltage; an integrator circuit configured to receive a sensing voltage generated at an end of the inductor and output an integral output based on the sensing voltage; an adder circuit configured to receive the error voltage and output an addition output based on the error voltage, the feedback voltage, and the reference voltage; and a controller configured to output the pulse width modulation signal by comparing the integral output with the addition output.
