Title:
Signal generation circuit, voltage converter and signal generation method
Document Type and Number:
Japanese Patent JP6332080
Kind Code:
B2
Abstract:
A CPU determines an ON-time setting value with which the generating unit generates a PWM signal having an ON time that is closest to the ON time corresponding to a product of a reference period and a target duty cycle, and sets the determined setting value in the generating unit. The CPU divides the ON time of the PWM signal based on the determined ON-time setting value, multiplies, by N, the period that corresponds to a result of the division, and specifies a period settable value with which a PWM signal having a period that is closest to a result of the multiplication is generated. The CPU determines period setting values for N periods based on a quotient and a remainder obtained by dividing the specified settable value by N, and sets the determined setting values in the generating unit for each period of the PWM signal.
