♠ 2 A, 1.5 MHz PWM isilawuli sokutshintshela esisezantsi esinolungiso oluhambelanayo
I-ST1S09 sisiguquli esisezantsi se-DC-DC esilungiselelwe ukunika amandla usetyenziso lwamandla ombane asezantsi.Inika amandla akhoyo angaphezulu kwe-2 A ngaphezulu koluhlu lwegalelo lombane ukusuka kwi-2.7 V ukuya kwi-6 V.
I-PWM ephezulu yokutshintsha i-frequency (1.5 MHz) ivumela ukusetyenziswa kwezinto ezincinci eziphezu komhlaba.
Ngaphezu koko, ekubeni i-rectifier ye-synchronous efunekayo idibaniswe, inani lamacandelo angaphandle liyancitshiswa libe lincinci: i-resistor divider, i-inductor kunye ne-capacitors ezimbini.IAmandla Umsebenzi olungileyo uhlala ebeka iliso kwi-voltage ephumayo.I-drain evulekileyo yeflegi ye-Power Good ikhutshwa xa i-voltage ephumayo ingaphakathi kommiselo.Ukongeza, i-ripple yemveliso ephantsiiqinisekiswa yimowudi yangoku yePWM topology kunye nokusetyenziswa kwe ESR ephantsi SMD capacitors ceramic.Isixhobo sikhuselwe ngokufudumeleyo kwaye imveliso yangoku ilinganiselwe ukunqanda umonakalo ofunekayokwisiphaluka esifutshane ngempazamo.I-ST1S09 ifumaneka kwi-DFN6 (3 x 3 mm) iphakheji.
