A 93.4% efficiency 42cc type-C power delivery adaptor with PMOS integration power line extension method

Abstract: This paper presents a dc-link capacitor reduction method with P-MOS integrated control method. When compared with SCR chopping method, this novel method can easily integrate the auxiliary switch and control function circuits into one simple chip. Furthermore, the P-MOS control ground can be directly connected onto bus ground. This connection method is convenient to integration and easy drive. The theoretical analysis and detailed control method is given. Furthermore, one ultra-high efficiency GaN-based 65W pro… Show more
