♠ 4.5V a i ka 18V INPUT, 2-A SYNCHRONOUS STEP DOWN VERTER ME KA HOʻOPIʻI FET
ʻO ka TPS54229 kahi mea hoʻololi i ka manawa D-CAP2™ mode synchronous buck converter. Hāʻawi ka TPS54229 i nā mea hoʻolālā ʻōnaehana e hoʻopiha i ka suite ovarious end's power bus regulators me ka uku kūpono, helu haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa i kēia manawa. Hoʻohana ka loop control nui no ka TPS54229 i ka mana mode D-CAP2™ e hāʻawi ana i ka pane transient wikiwiki me ka ʻole o nā ʻāpana uku o waho. Loaʻa i ka TPS54229 kahi kaapuni proprietary e hiki ai i ka hāmeʻa ke hoʻohana i nā capacitors hoʻohālikelike haʻahaʻa like haʻahaʻa (ESR), e like me POSCAP a i ʻole SP-CAP, a me nā capacitors ceramic ultra-low ESR. Hoʻohana ka hāmeʻa mai 4.5-V a i 18-V VIN hoʻokomo. Hiki ke ho'olālā 'ia ka volta ho'opuka ma waena o 0.76 V a me 7 V. Ho'okomo pū ka mea hana i kahi manawa ho'omaka palupalu hiki ke ho'ololi. Loaʻa ka TPS54229 i loko o ka pūʻolo DDA 8-pin, a hoʻolālā ʻia e hana mai -40°C a 85°C.
• Hiki i ke ʻano D-CAP2™ ke pane wikiwiki
• Haʻahaʻa Output Ripple a ae ia Ceramic Output Capacitor
• Laulā Voltage VIN Input Voltage: 4.5 V a i 18 V
• Laulā Voltage Output: 0.76 V a i 7.0 V
• ʻO nā FET i hoʻohui ʻia ʻoi loa ka maikaʻi loa no nā noi haʻahaʻa Duty Cycle
– 160 mΩ (ʻaoʻao kiʻekiʻe) a me 110 mΩ (ʻaoʻao haʻahaʻa)
• Kiekie Efficiency, emi ma mua o 10 μA ma ka pani ana
• Kiʻekiʻe Initial Bandgap Reference Accuracy
• Hoʻomaka palupalu hiki ke hoʻololi
• Hoʻomaka ʻoluʻolu mua
• 650-kHz ka pinepine hoʻololi (fSW)
• Kaapuni ma ke kaapuni ma luna o ka palena o kēia manawa
• Laulā o nā noi no ka haʻahaʻa Voltage System
– Kikohoʻe TV mana lako
- Nā mea pāʻani Blu-ray Disc™ wehewehe kiʻekiʻe
– ʻO ka ʻupena Home Terminal
– Pahu Hoʻonohonoho Kikohoʻe (STB)
