A novel pulse frequency modulation step-up dc-dc converter with maximum power conversion of 91.91% and steady-state accuracy of 0.33% is presented in this letter. The high efficiency and exact output are achieved by a dynamic stored energy technique that enhances utility rate of energy with less power consumption. This technique uses a dynamic sensing current controller and a load current detector...
This paper presents an exact and high-efficiency PFM dc-dc boost converter designed with a standard TSMC 3.3/5 V 0.35-mum CMOS technology. The proposed boost converter utilizes a dynamic stored energy technique to reduce output voltage variation and raise power conversion efficiency. This result is realized using a dynamic stored energy controller and a load current detector that accurately generates...
