♠ 2 A, 1.5 MHz PWM isilawuli esishintshela phansi esinokulungiswa okuvumelanayo
I-ST1S09 iyisiguquli se-DC-DC esiya phansi esenzelwe ukunika amandla izinhlelo zokusebenza zamandla kagesi aphuma kancane.Inikeza amandla amanje angaphezu kuka-2 A ngaphezu kwebanga le-voltage yokufaka ukusuka ku-2.7 V ukuya ku-6 V.
Imvamisa yokushintsha ye-PWM ephezulu (1.5 MHz) ivumela ukusetshenziswa kwezingxenye ezincane zokukhweza phezulu.
Ngaphezu kwalokho, njengoba i-synchronous rectifier edingekayo ihlanganisiwe, inani lezingxenye zangaphandle lincishiswa libe lincane: i-resistor divider, i-inductor nama-capacitor amabili.IAmandla Umsebenzi omuhle uqapha ngokuqhubekayo i-voltage ephumayo.Ifulegi le-Power Good liyakhishwa uma i-voltage ephumayo ingaphakathi kwesimiso.Ngaphezu kwalokho, a low okukhipha ripple kuyintokuqinisekiswe imodi yamanje ye-PWM topology kanye nokusetshenziswa kwama-ceramic capacitor e-ESR SMD aphansi.Idivayisi ivikelwe ngendlela eshisayo futhi okukhiphayo kukhawulelwe ukuze kuvinjelwe umonakalo ongenzekakumjikelezo omfishane ngephutha.I-ST1S09 iyatholakala kuphakheji ye-DFN6 (3 x 3 mm).
