♠ TPS62902, 3-V ki te 17-V, Te Tino Pai me te Kaihuri IQ Buck iti i roto i te 1.5-mm × 2-mm QFN Package
Ko te TPS62902 he kaitahuri DC-DC tino pai, iti, ngawari hoki te tukutahi he ngawari ki te whakamahi.Ko te auau whakawhiti ka taea te 2.5 MHz, 1.0 MHz ranei ka taea te whakamahi i nga whakaurunga iti me te tuku urupare tere tere.Ka tautokohia e te taputapu te tika VOUT teitei o ± 1% me te topology DCS-Mana.Ko te awhe ngaohiko whakauru whanui o te 3-V ki te 17-V e tautoko ana i te maha o nga whakaurunga ingoa, penei i te reera tuku 12-V, te Li-Ion kotahi-putau-maha ranei, me nga reera 5-V, 3.3-V ranei.
Ka taea e te TPS62902 te whakauru aunoa i te aratau whakaora mana (mehemea ka tohua te PFM/PWM aunoa) i nga kawenga marama kia mau tonu ai te kaha.I tua atu, ki te whakarato i te tino pai ki nga kawenga iti rawa, he iti noa te naianei o te taputapu he 4 µA.AEE, ki te whakahohea, ka whakarato i te tino pai puta noa i te VIN, VOUT, me te uta o naianei.Kei roto i te taputapu he whakauru S-CONF/MODE ki te whakarite i te wehewehenga o roto/waho, te auau whakawhiti, te tukunga ngaohiko whakaputa, me te aratau whakaora mana aunoa, te mahi PWM kaha ranei.
Kei te waatea te taputapu i roto i te kete iti 9-titi VQFN te ine 1.50 mm × 2.00 mm me te 0.5-mm pitch.
• He tino pai mo te huringa mahi whanui me te awhe kawenga

• Iti 1.5-mm × 2.0-mm VQFN mōkihi me te 0.5-mm te papa
• Tae atu ki te 2-A te naianei putanga tonu
• ±0.9% te tika o te ngaohiko urupare puta noa i te mahana (-40°C ki te 150°C)
• Kōwhiringa ngaohiko putanga ka taea te whirihora:
– VFB wehewehe waho: 0.6 V ki te 5.5 V
– VSET whakawehenga o roto: 16 nga whiringa i waenga i te 0.4 V me te 5.5 V
• DCS-Control™ topology with 100% mode
• He tino ngawari me te ngawari ki te whakamahi
– Pinout arotau mo te ararere papa-kotahi

– Power pai putanga
– Ka taea te kowhiri i te tukunga putanga kaha
– Te tiimata ngawari me te aroturuki
• Karekau he puritanga bootstrap o waho e hiahiatia ana
• Hangaia he hoahoa ritenga ma te whakamahi i te TPS62902 ma te whakamahi i te WEBENCH® Power Designer
• te aunoatanga wheketere me te mana whakahaere
• Hangaia aunoatanga
• Pokapū raraunga me te rorohiko hinonga
• Nga punaha taraiwa motuka
• Te tuku hiko
• PC me nga pukamahi
