♠ TPS61252 encinci 1.5-A iBoost Converter kunye noHlelo olunoHlelelayo loMda wangoku
Isixhobo se-TPS61252 sibonelela ngesisombululo sombane kwiimveliso eziqhutywa yi-alkaline yeeseli ezintathu, i-NiCd okanye i-NiMH ibhetri, okanye i-cell-cell Li-Ion okanye i-Li-polymer ibhetri. Uluhlu olubanzi lwamandla ombane lufanelekile ukunika amandla usetyenziso oluphathwayo njengeefowuni eziphathwayo okanye iiperipheral zekhompyuter. Isixhobo sinesistor programmable (RILIM) igalelo lomda wangoku kwaye ifanelekile kwiindidi ezahlukeneyo zezicelo.
Ngexesha lomthwalo okhanyayo, isixhobo singena ngokuzenzekelayo kwimodi yokutsiba (PFM), evumela umguquli ukuba agcine i-voltage efunekayo yokuphuma, ngelixa udweba kuphela i-30 μA i-quiescent yangoku kwibhetri. Oku kuvumela ukusebenza kakuhle kowona mandla asezantsi athuleyo.
I-TPS61252 ivumela ukusetyenziswa kwee-inductors ezincinci kunye ne-capacitors ukufikelela kwisisombululo esincinci. Ithuba lokunciphisa umda wangoku ngumxhasi wangaphandle unikezela ukusetyenziswa okunokwenzeka kwee-inductors ezincinci ngokwasemzimbeni kunye nemisinga ephantsi yokulinganisa ukuqhubela phambili ukunciphisa ubungakanani besisombululo esipheleleyo sobonelelo lwamandla. Ngexesha lokuvala, umthwalo unqanyulwe ngokupheleleyo kwibhetri. I-TPS61252 ifumaneka kwi-8-pin ye-WSON iphakheji yokulinganisa i-2 mm × 2 mm (DSG).
