♠ TPS61252 Tiny 1.5-A Boost Converter e nang le Moedi oa Hona Joale oa Kenyelletso
Sesebelisoa sa TPS61252 se fana ka tharollo ea phepelo ea motlakase bakeng sa lihlahisoa tse tsamaisoang ke betri ea alkaline ea lisele tse tharo, NiCd kapa NiMH, kapa betri ea sele e le 'ngoe ea Li-Ion kapa Li-polymer. Mefuta e mengata ea motlakase ea ho kenya e loketse ho matlafatsa lits'ebetso tse nkehang joaloka mehala ea cellular kapa li-peripheral tsa khomphutha. Sesebelisoa se na le moeli oa ho kenya oa esistor programmable (RILIM) mme se loketse mefuta e mengata ea lits'ebetso.
Nakong ea meroalo e bobebe, sesebelisoa se kenella ka mokhoa oa skip mode (PFM), e lumellang converter hore e boloke motlakase o hlokahalang, ha e ntse e hula 30 μA e khutsitseng hona joale ho tsoa ho betri. Sena se lumella ho sebetsa hantle haholo ha maqhubu a khutsitse a tlase.
TPS61252 e lumella tšebeliso ea li-inductors tse nyane le li-capacitor ho fihlela boholo ba tharollo e nyane. Monyetla oa ho fokotsa moeli oa hajoale ke mohanyetsi oa kantle o fana ka ts'ebeliso e ka bang teng ea li-inductors tse nyane le tse nyane tse nang le maqhubu a tlase ho fokotsa boholo ba tharollo ea phepelo ea motlakase. Nakong ea ho koala, mojaro o hakoa ka ho feletseng betri. TPS61252 e fumaneha ka har'a sephutheloana sa WSON sa 8-pin se lekanyang 2 mm × 2 mm (DSG).
