A new design scheme, with the sample current circuit by the use of MAX471 and regulate component of P type MOSFET, is presented in this paper. With the use of MAX471 and ultra low on-resistance components P-MOSFET, the new power circuit results in a very low drop-out voltage, and conversion efficiency is very high, presenting a very good application future.
