2.5-A inoenderera kuburitsa ikozvino
Integrated synchronous rectification
Current mode control
Minimum switch ON nguva: 60 ns
2.1-MHz switching frequency nePFM uye yekumanikidza-PWM-modhi sarudzo (HSOIC)
2.1-MHz switching frequency nekumanikidzwa-PWM modhi chete (WSON)
Frequency synchronization kune yekunze wachi
Muripo wemukati wekureruka kwekushandisa
75-µA runyararo ikozvino pasina mutoro
Soft kutanga kuita prebiased mutoro
High duty-cycle operation inotsigirwa
Precision inogonesa kuisa
Output short-circuit dziviriro ine hiccup mode
Kudzivirira kupisa
8-Pin HSOIC ine PowerPAD™ package
12-Pini WSON inonyorovesa flanks package ine PowerPAD™
Shandisa iyoLMZM33603module yekukurumidza nguva yekutengesa
Gadzira dhizaini yakasarudzika uchishandisa iyo LMR23625 neiyoWEBENCH Power Designer
Tsanangudzo yeLMR23625
Iyo LMR23625 SIMPLE SWITCHER iri nyore kushandisa 36-V, 2.5-A synchronous step-down regulator.Nehupamhi hwekuisa kubva ku4 V kusvika ku36 V, chishandiso chakakodzera kune akasiyana maindasitiri ekushandisa kwekugadzirisa magetsi kubva kune asina kudzorwa zvinyorwa.Peak yazvino-modhi yekudzora inoshandiswa kuwana yakapusa yekudzora-loop muripo uye kutenderera-ne-kutenderera ikozvino kudzikisira.Ikozvino yakanyarara ye75 µA inoita kuti ive yakakodzera kune mabhatiri-powered masisitimu.Iyo yekupedzisira-yakaderera 2 µA yekudzima ikozvino inogona kuwedzera hupenyu hwebhatiri.Muripo wemukati weloop zvinoreva kuti mushandisi akasununguka kubva kune rinonetesa basa rekugadzira loop muripo.Izvi zvinoderedzawo zvikamu zvekunze.
Chishandiso chine sarudzo yeyakagadziriswa-frequency FPWM modhi kuti iwane diki inobuda-voltage ripple pakuremerwa kwakareruka.Mhuri yakawedzera yeHSOIC inowanikwa mu1-A (LMR23610) uye 3-A (LMR23630) inotakura zvazvino sarudzo mupini-kupini-pini inoenderana mapakeji inobvumira yakapusa, yakakwana PCB marongero.Iyo chaiyo inogonesa yekuisa inobvumira kurerutsa yekudzora kudzora uye sisitimu simba kutevedzana.Zvidziviriro zvekudzivirira zvinosanganisira cycle-by-cycle current limit, hiccup-mode short-circuit protection uye thermal shutdown nekuda kwekunyanya kupera simba.
1. Ndivanaani vashandi mudhipatimendi rako reR & D?Ndezvipi zvidzidzo zvako?
-R & D Mutungamiriri: gadzira chirongwa chekambani chenguva refu R & D uye ubate gwara rekutsvaga nekusimudzira;Tungamira uye tarisa r&d dhipatimendi kuti iite kambani r&d zano uye yegore R&D chirongwa;Dzora kufambira mberi kwekugadzirwa kwechigadzirwa uye gadzirisa chirongwa;Gadzira yakanakisa chigadzirwa chekutsvagisa uye timu yekusimudzira, yekuongorora uye yekudzidziswa ine chekuita nehunyanzvi vashandi.
R & D Maneja: gadzira chigadzirwa chitsva R & D kuronga uye kuratidza kugona kwechirongwa;Tarisa uye gadzirisa kufambira mberi uye kunaka kwer&d basa;Tsvagurudza kugadzirwa kwechigadzirwa chitsva uye kurudzira mhinduro dzinoshanda zvinoenderana nezvinodiwa nevatengi munzvimbo dzakasiyana
Vashandi veR&d: unganidza uye gadzirisa data rakakosha;Computer programming;Kuita zviedzo, bvunzo uye ongororo;Gadzirira zvinhu uye zvishandiso zvekuyedza, bvunzo uye ongororo;Rekodha data yekuyera, ita kuverenga uye gadzira machati;Ita ongororo dzenhamba
2. Ndeipi yako chigadzirwa tsvakurudzo uye budiriro pfungwa?
-Kufunga kwechigadzirwa uye sarudzo yechigadzirwa pfungwa uye yekuongorora tsanangudzo yechigadzirwa uye dhizaini dhizaini uye kusimudzira chigadzirwa kuyedzwa uye kusimbiswa kwekutanga kumusika.
