♠ TPS62902, 3-V kugeza 17-V, Ubushobozi buhanitse hamwe na IQ Buck ihindura muri 1.5-mm × 2-mm QFN
TPS62902 nigikorwa cyiza cyane, gito, kandi cyoroshye guhuza intambwe-hasi DC-DC ihindura byoroshye gukoresha. Guhitamo guhinduranya inshuro ya 2.5 MHz cyangwa 1.0 MHz itanga ikoreshwa rya inductors nto kandi itanga igisubizo cyihuse. Igikoresho gishyigikira VOUT yukuri ya ± 1% hamwe na DCS-Igenzura topologiya. Umuyoboro mugari winjiza wa 3-V kugeza 17-V ushyigikira inyongeramusaruro zinyuranye, nka 12-V itanga imiyoboro, selile imwe cyangwa selile-Li-Ion, na 5-V cyangwa 3.3-V.
TPS62902 irashobora guhita yinjira muburyo bwo kubika ingufu (niba auto PFM / PWM yatoranijwe) kumitwaro yoroheje kugirango ikomeze gukora neza. Byongeye kandi, kugirango utange imikorere ihanitse ku mizigo mito cyane, igikoresho gifite icyerekezo gisanzwe cyo gutuza cya 4 µA. AEE, niba ishoboye, itanga imikorere myiza muri VIN, VOUT, hamwe nuburemere bugezweho. Igikoresho kirimo S-CONF / MODE ibyinjijwe kugirango ushireho imbere / hanze igabanya, guhinduranya inshuro nyinshi, gusohora ingufu za voltage, hamwe nuburyo bwo kuzigama amashanyarazi cyangwa gukora PWM ku gahato.
Igikoresho kiraboneka muri pake ntoya 9-pin VQFN ipima mm 1,50 mm × 2.00 mm hamwe na 0.5-mm.
