Low‐power pulse width modulation (PWM) for high‐frequency DC–DC converters [PDF]
Electronics Letters, 2018 A low‐power pulse width modulation (PWM) control circuit for high‐frequency switching direct current (DC)–DC converters based on a one‐shot circuit is proposed. The proposed PWM control circuit eliminates the use of a high‐power comparator and ramp generator that is conventionally used to generate the PWM waveform.
