♠ TPS6229x 1-A Inyathelo ezantsi Converter kwi 2 x 2 DRV Package
Izixhobo ze-TPS6229x zisebenza ngokugqibeleleyo kwi-synchronous step down DC/DC converters elungiselelwe usetyenziso oluphathwayo olunebhetri. Banikezela ukuya kuthi ga kwi-1000-mA yemveliso yangoku kwiseli enye ye-Li-ion.
Ngoluhlu lwamandla ombane we-2.3 V ukuya kwi-6.0 V, izixhobo zixhasa iibhetri ezinoluhlu olwandisiweyo lwamandla ombane kwaye zifanelekile ukunika amandla usetyenziso oluphathwayo njengeefowuni eziphathwayo kunye nezinye izixhobo eziphathwayo.
Izixhobo ze-TPS6229x zisebenza kwi-2.25-MHz i-frequency switching frequency kunye nokufaka imowudi yokulondoloza amandla kwimisinga yomthwalo wokukhanya ukugcina ukusebenza okuphezulu phezu koluhlu lwangoku lomthwalo.
Imowudi yokonga amandla ilungiselelwe i-ripple voltage yemveliso ephantsi. Kusetyenziso lwengxolo ephantsi, izixhobo zinokunyanzelwa ukuba zibe kwimowudi esisigxina ye-pulse wide modulation (PWM) ngokutsalela i-MODE ipini phezulu. Kwimodi yokuvala, ukusetyenziswa kwangoku kuncitshiswa ukuya ngaphantsi kwe-1 μA. Izixhobo ze-TPS6229x zivumela ukusetyenziswa kwee-inductors ezincinci kunye ne-capacitors ukufikelela kwisisombululo esincinci.
Izixhobo ze-TPS6229x zisebenza kudederhu lobushushu bomoya osimahla obuphakathi -40°C ukuya kuma-85°C. Izixhobo zifumaneka kwi-2-mm × 2-mm 6-pin ye-WSON package (DRV).
