ST1S09 mai jujjuyawar DC-DC ne mai saukar ungulu wanda aka inganta don yin ƙarfin aikace-aikacen ƙarancin wutar lantarki.Yana samar da na yanzu fiye da 2 A akan kewayon shigarwar ƙarfin lantarki daga 2.7 V zuwa 6 V.
Babban mitar sauya PWM (1.5 MHz) yana ba da damar yin amfani da ƙananan abubuwan da aka gina-motsi.
Bugu da ƙari, tun da aka haɗa mai gyara aiki tare da ake buƙata, adadin abubuwan waje yana raguwa zuwa mafi ƙarancin: mai rarraba resistor, inductor da capacitors biyu.ThePower Good aiki ci gaba da lura da fitarwa ƙarfin lantarki.Buɗewar magudanar ruwa Power Kyakkyawan tuta ana fitar da ita lokacin da ƙarfin fitarwa yana cikin ƙa'ida.Bugu da ƙari, ƙananan fitarwa negaranti ta yanayin PWM topology na yanzu da kuma ta amfani da ƙananan ESR SMD yumbu capacitors.Na'urar tana da kariya ta zafi kuma ana iyakance abin da ake fitarwa don hana lalacewazuwa gajeriyar kewayawa ta bazata.Ana samun ST1S09 a cikin kunshin DFN6 (3 x 3 mm).
