♠ TPS6229x 1-A mea hoʻololi iho i lalo ma 2 x 2 DRV Pūʻolo
ʻO nā hāmeʻa TPS6229x he mea hoʻololi maikaʻi loa ia i lalo o ka DC/DC i hoʻololi ʻia no nā noi uila uila.Hāʻawi lākou a hiki i ka 1000-mA hoʻopuka i kēia manawa mai kahi kelepona Li-ion hoʻokahi.
Me ka mana o ka volta input o 2.3 V a 6.0 V, kākoʻo nā mea hana i nā pila me ka laulā voli ākea a kūpono hoʻi no ka hoʻohana ʻana i nā noi lawe lima e like me nā kelepona paʻalima a me nā mea lawe lima ʻē aʻe.
Hoʻohana nā mea TPS6229x ma 2.25-MHz hoʻololi paʻa i ka alapine a hoʻokomo i ka hana hoʻopakele mana ma nā kaha haʻahaʻa māmā e hoʻomau i ka hana kiʻekiʻe ma luna o ka pae holoʻokoʻa o kēia manawa.
Hoʻomaʻamaʻa ʻia ke ʻano hoʻopakele mana no ka ripple puʻupuʻu haʻahaʻa haʻahaʻa.No nā noi haʻahaʻa haʻahaʻa, hiki ke hoʻoikaika ʻia nā mea hana i ka mode frequency pulse width modulation (PWM) ma ka huki ʻana i ka pine MODE kiʻekiʻe.Ma ke ʻano pani ʻana, hoʻemi ʻia ka hoʻohana ʻana i kēia manawa ma lalo o 1 μA.Hiki i nā polokalamu TPS6229x ke hoʻohana i nā inductors liʻiliʻi a me nā capacitors e hoʻokō i kahi nui liʻiliʻi.
Hoʻohana ʻia nā mea hana TPS6229x ma luna o ka pae wela o ka ea manuahi o –40°C a i 85°C.Loaʻa nā mea hana i loko o kahi pūʻolo WSON 2-mm × 2-mm 6-pin WSON (DRV).
