Abstract
Official abstract text for this publication.
A control method for preventing an output voltage of a buck switching regulator from falling when an input voltage of the buck switching regulator falls includes: converting the input voltage into a charging current; determining a duty cycle of the buck switching regulator according to the charging current and the output voltage; and adjusting a switching frequency of a pulse width modulation signal in the buck switching regulator when the input voltage falls to a specific voltage and an off time of the pulse width modulation signal reaches a minimum value, in order to change the duty cycle to prevent the output voltage from falling.
First claim
Opening claim text (preview).
What is claimed is: 1. A control method for preventing an output voltage of a buck switching regulator from falling when an input voltage of the buck switching regulator falls, the control method comprising: converting the input voltage into a charging current; determining a duty cycle of the buck switching regulator according to the charging current and the output voltage; and adjusting a switching frequency of a pulse width modulation signal in the buck switching regulator w…
