摘要

提出了一种新的用于降压型DC-DC变换器的PWM/PFM混合模式自动变换技术。该方法利用比较器的传播延迟来确定模式改变点，而无需添加复杂的PMW/PFM混合模式控制器。提出的概念使混合型降压DC-DC变换器的实现变得紧凑和简单。仿真结果表明，降压型DC-DC变换器可以实现PWM和PFM模式之间的无缝转换。PWM和PFM模式的最大效率分别高达97%和94%。

A buck DC-DC converter with a novel PWM/PFM hybrid-mode auto-change technique

A novel PWM/PFM hybrid-mode auto-change technique for buck DC-DC converter is proposed. The proposed technique utilizes the comparator propagation delay to decide the mode changing point without adding complicated PMW/PFM hybrid-mode controller. The proposed concept enables compact and simple implementation of hybrid-mode buck DC-DC converter. Simulation results show that the buck DC-DC converter can achieve seamless transition between PWM and PFM mode. The maximum efficiency of PWM and PFM mode are up to 97% and 94% respectively.
