A Synchronous Boost Regulator with PWM/PFM Mode Operation

摘要：

This paper presents a synchronous boost regulator with PWM/PFM mode of operation.It uses synchronous rectification architecture to reduce the conduction loss and improve the efficiency.Furthermore,this paper features a two-level soft-start circuit which prevents the presence of large current generation during system start-up. The simulation results show an efficiency of more than 0 with an input voltage range of 2..2 and with a load current of mA to 200mA. This regulator is suitable for ion battery supply application.It uses TSMC s 0.um 2P M CMOS process.
