用于可变开关噪声抑制的无杂散控制电流模式滞回Buck变换器

This paper proposes a current-mode hysteretic buck converter with a spur-free constant-cycle frequency-hopping controller that fully eliminates spurs from the switching noise spectrum irrespective of variations in the switching frequency and operating conditions. As a result, the need for frequency regulation loops to ensure nonvarying switching frequency (i.e., fixed spurs location) in hysteretic...
