♠ I-TPS62902, 3-V ukuya ku-17-V, Ukusebenza Kahle kanye ne-Low IQ Buck Converter ku-1.5-mm × 2-mm QFN Iphakheji
I-TPS62902 iyisiguquli se-DC-DC esisebenza kahle kakhulu, esincane, futhi esivumelana nezimo esiguquguqukayo esisebenziseka kalula. Imvamisa yokushintsha ekhethekayo engu-2.5 MHz noma 1.0 MHz ivumela ukusetshenziswa kwama-inductors amancane futhi inikeze impendulo esheshayo yesikhashana. Idivayisi isekela ukunemba okuphezulu kwe-VOUT okungu-± 1% nge-DCS-Control topology. Ibanga elibanzi lokufakwa kwamandla kagesi elingu-3-V ukuya ku-17-V lisekela okokufaka okuhlukahlukene okuzisholo, okufana namalayili wokuphakelayo angu-12-V, iseli elilodwa noma i-Li-Ion yamaseli amaningi, kanye nomzila ongu-5-V noma 3.3-V.
I-TPS62902 ingangena ngokuzenzakalelayo kumodi yokonga amandla (uma i-auto PFM/PWM ikhethiwe) emithwalweni ekhanyayo ukuze kugcinwe ukusebenza kahle okuphezulu. Ukwengeza, ukuze kuhlinzekwe ukusebenza kahle okuphezulu emithwalweni emincane kakhulu, idivayisi inomoya othule ojwayelekile ophansi ongu-4 µA. I-AEE, uma inikwe amandla, inikeza ukusebenza kahle okuphezulu kuyo yonke i-VIN, i-VOUT, nokulayisha kwamanje. Idivayisi ihlanganisa okokufaka kwe-S-CONF/MODE ukusetha isihlukanisi sangaphakathi/sangaphandle, imvamisa yokushintsha, ukukhishwa kwe-voltage okukhiphayo, kanye nemodi yokonga amandla okuzenzakalelayo noma ukusebenza kwe-PWM okuphoqelelwe.
Idivayisi itholakala ngephakeji encane engu-9-pin VQFN enesilinganiso esingu-1.50 mm × 2.00 mm nephimbo elingu-0.5-mm.
• Ukusebenza kahle okuphezulu komjikelezo wemisebenzi ebanzi kanye nebanga lomthwalo

• ±0.9% ukunemba kwevolthi yempendulo kulo lonke izinga lokushisa (-40°C ukuya ku-150°C)
• Izinketho zamandla kagesi wokuphumayo ezilungisekayo:
- Isihlukanisi sangaphandle se-VFB: 0.6 V kuya ku-5.5 V
- Isihlukanisi sangaphakathi se-VSET: Izinketho eziyi-16 phakathi kuka-0.4 V no-5.5 V
• I-DCS-Control™ topology enemodi engu-100%.
• Iguquguquka kakhulu futhi kulula ukuyisebenzisa
- I-pinout elungiselelwe yomzila wesendlalelo esisodwa
– Nika amandla ngokunembile okokufaka
- I-PWM ephoqelelwe noma imodi yokonga amandla okuzenzakalelayo
- Amandla okukhipha okuhle
- Ukukhipha okusebenzayo okukhethiwe
- Isiqalo esithambile esilungisekayo nokulandelela
