Ibiranga
1.Yinjije 26 mΩ na 19 mΩ MOSFETS
2.Gabanya Gariyamoshi: 1.6 V kugeza 17 V kuri PVIN
3.200-kHz kugeza kuri 1.6-MHz Guhindura inshuro
4.Guhuza isaha yo hanze
5.0.8 V ± 1% Umuvuduko ukabije w'ubushyuhe bukabije
6.Kureka 2-µA Guhagarika Quiescent Yubu
7.Monotonic Gutangira-Hejuru Mubisubizo Byabanjirije
8. - 40 ° C kugeza kuri 150 ° C Ubushyuhe bukora Ubushyuhe
Urwego
1.Guhindura Buhoro Buhoro Gutangira no Gukurikirana Imbaraga
2.Imbaraga nziza zisohoka mugukurikirana kuri Undervoltage na
Gukurikirana birenze urugero
Guhindura Iyinjiza Undervoltage Ifunga

Kora Igishushanyo cyihariye Ukoresheje TPS54620
Hamwe na WEBENCH Imbaraga Zishushanya
Porogaramu
1.Ubucucike Bwinshi Bwakwirakwijwe Sisitemu Yingufu
2.Icyerekezo Cyiza cyo Kugenzura Imizigo
3.Umuyoboro mugari, Umuyoboro hamwe na Optical
Itumanaho Ibikorwa Remezo Ibisobanuro TPS54620 murwego rwo hejuru rwa 3.50 mm ×
3.50 mm ya QFN yamashanyarazi niyuzuye yuzuye 17-V, 6-A, ihuza, ihinduranya-hasi ihinduranya ibishushanyo bito binyuze muburyo bunoze kandi igahuza MOSFET yo murwego rwo hejuru kandi yo hepfo.Ubundi kuzigama umwanya bigerwaho binyuze muri iki gihe uburyo bwo kugenzura, bugabanya kubara ibice, no muguhitamo inshuro nyinshi zo guhinduranya, kugabanya ikirenge cya inductor.Ibisohoka voltage itangira-igenzurwa na SS / TR pin yemerera gukora nkibikoresho bitanga amashanyarazi wenyine cyangwa mugukurikirana ibihe.Imbaraga zikurikirana nazo zirashoboka mugushiraho neza ubushobozi hamwe no gufungura-imiyoboro yimbaraga nziza.Ukuzenguruka-by-cycle bigarukira kuruhande rwo hejuru FET irinda igikoresho mugihe kirenze urugero kandi ikongerwaho nimbaraga zo hasi zishakisha imipaka irinda guhunga.Hariho kandi uruhande rwo hasi rwo kurohama rugarukira ruzimya uruhande rwo hasi MOSFET kugirango wirinde gukabya gukabije.Guhagarika amashyuza bihagarika igice mugihe ubushyuhe bwo gupfa burenze ubushyuhe bwo guhagarika ubushyuhe.
