♠ TPS54388C-Q1 Imodoka 2.95-V kugeza 6-V, 3-A, 2-MHz Guhuza Buck Guhindura
Igikoresho cya TPS54388C-Q1 nigikoresho cyuzuye-6-V, 3-A, guhuza intambwe-hasi-ya-moderi ihindura hamwe na MOSFET ebyiri zahujwe.
Igikoresho cya TPS54388C-Q1 gifasha ibishushanyo bito muguhuza MOSFETs, gushyira mubikorwa uburyo-bwo kugenzura kugirango ugabanye ibice byo hanze, kugabanya ingano ya inductor ukoresheje uburyo bwo guhinduranya inshuro 2-MHz, no kugabanya ikirenge cya IC hamwe na 3-mm × 3-mm yubushyuhe bwa QFN.
Igikoresho cya TPS54388C-Q1 gitanga amabwiriza nyayo kumitwaro itandukanye hamwe na ± 1% ya voltage yerekana (Vref) hejuru yubushyuhe.
Byahujwe na 12-mΩ MOSFETs na 515-μA bisanzwe bitanga isoko bigezweho. Kwinjira muburyo bwo kuzimya ukoresheje pin igabanya kugabanuka gutanga kugeza kuri 5.5 µA, bisanzwe.
Igenamigambi ryimbere ya undervoltage iri kuri 2.45 V, ariko gutangiza urutonde hamwe numuyoboro urwanya rezo kuri pin irashobora kongera igenamiterere. Buhoro-gutangira pin ishyiraho ibisohoka-voltage gutangira-ramp. Gufungura-imiyoboro yimbaraga-nziza yerekana igihe ibisohoka biri muri 93% kugeza 107% bya voltage yizina ryayo.
Inshuro inshuro nyinshi hamwe no guhagarika ubushyuhe birinda igikoresho mugihe kirenze urugero.
• AEC-Q100-yujuje ibyangombwa byo gukoresha imodoka:
- Icyiciro cy'ubushyuhe 1: –40 ° C kugeza + 125 ° C, TA
• Umutekano wimikorere-Birashoboka
- Inyandiko ziboneka zifasha igishushanyo mbonera cya sisitemu yumutekano
• MOSFET ebyiri ebyiri-mΩ (zisanzwe) kugirango zikore neza kuri 3-A imizigo
• 200-kHz kugeza kuri 2-MHz guhinduranya inshuro
• 0.8 V ± 1% ya voltage yerekana ubushyuhe (- 40 ° C kugeza + 150 ° C)
• Guhuza isaha yo hanze
• Guhindura buhoro buhoro gutangira no gukurikirana
• UV na OV imbaraga-nziza zisohoka
• –40 ° C kugeza kuri + 150 ° C ikora ubushyuhe bwubushyuhe
• Ubushyuhe bwongerewe 3-mm × 3-mm 16-pin WQFN
• Ipine ijyanye na TPS54418
• Ibicuruzwa bishya biboneka: TPS62813-Q1, 6-V ihindura intambwe muri 2-mm x 3-mm ya QFN yamashanyarazi hamwe nimpande zuzuye.
• Amashanyarazi make, sisitemu yububasha bwinshi
• Ingingo-yumutwaro amabwiriza ya DSP ikora cyane, FPGAs, ASICs, na microprocessors
• Umuyoboro mugari, imiyoboro, n'ibikorwa remezo by'itumanaho rya optique
