TPS61252DSGT Nā Hoʻoponopono Voltage Hoʻololi 3.5MHz1.5A92% Eff Boost Converter

Hāʻawi ka hāmeʻa TPS61252 i kahi hopena hoʻolako mana no nā huahana i hoʻohana ʻia e ka ʻekolu-cell alkaline, NiCd a i ʻole NiMH pākahiko, a i ʻole ka pākahi Li-Ion a i ʻole Li-polymer pākahi. He mea kūpono ke ʻano o ka puʻuwai hoʻokomo ākea i nā noi lawe lima e like me nā kelepona paʻalima a i ʻole nā ​​​​peripherals kamepiula. Loaʻa i ka hāmeʻa kahi palena hoʻokomo esistor programmable (RILIM) i kēia manawa a kūpono no nā ʻano noi like ʻole.

I ka wā o nā haʻahaʻa māmā, komo koke ka mea hana i ke ʻano skip mode (PFM), ka mea e hiki ai i ka mea hoʻololi ke mālama i ka volta puka i koi ʻia, ʻoiai e huki wale ana i ka 30 μA quiescent current mai ka pākaukau. Hāʻawi kēia i ka hana kiʻekiʻe loa i nā au haʻahaʻa haʻahaʻa.

ʻAe ʻo TPS61252 i ka hoʻohana ʻana i nā inductors liʻiliʻi a me nā capacitors e hoʻokō i kahi liʻiliʻi liʻiliʻi. ʻO ka hiki ke hōʻemi i ka palena o kēia manawa e kahi resistor o waho e hāʻawi i ka hoʻohana ʻana i nā inductors liʻiliʻi a me nā ʻano haʻahaʻa haʻahaʻa e hōʻemi hou i ka nui o ka hopena o ka lako mana. I ka wā o ka pani ʻana, ua hemo loa ka ukana mai ka pākaukau. Loaʻa ka TPS61252 i loko o kahi pūʻolo 8-pin WSON me ke ana ʻana he 2 mm × 2 mm (DSG).
