-Umuvuduko mwinshi wa HB LED Abashoferi hamwe na Integrated High-Side Current Sense
MAX16833, MAX16833B, MAX16833C, MAX16833D, na MAX16833G ni imashini igezweho-igenzurwa na LED igendanwa kugirango izamure, izamura amafaranga, SEPIC, iguruka, hamwe na topologiya yo hejuru. Umushoferi ucuramye wagenewe gutwara p-umuyoboro wo hanze ukurikirana hamwe na LED umugozi wa pro vide yagutse cyane. Iyi mikorere itanga byihuse cyane PWM ihinduranya kuri LED ntamashanyarazi arenze urugero cyangwa amashanyarazi. Usibye dimingi ya PWM, IC zitanga analog dimming ukoresheje DC yinjiye muri ICTRL. ICs yumva urumuri rwa LED kuruhande rwo hejuru rwumugozi wa LED.
Rististoriste imwe kuva RT / SYNC kugeza kubutaka ishyiraho inshuro yo guhinduranya kuva 100kHz ikagera kuri 1MHz, mugihe ikimenyetso cyamasaha yo hanze gishobora guhuzwa na RT / SYNC cyemerera IC guhuza isaha yo hanze. Muri MAX16833 / C / G, inshuro zo guhinduranya zishobora kwerekanwa kugirango zikwirakwizwe. MAX16833B / D ahubwo itanga voltage ya 1.64V hamwe no kwihanganira 2%.
IC ikora hejuru ya 5V-kugeza kuri 65V itanga kandi ikubiyemo 3A sink / umushoferi wamarembo yo gutwara ibinyabiziga MOSFET mumashanyarazi akomeye ya LED. Ibintu byiyongereyeho birimo amakosa-yerekana ibyasohotse (FLT) kubintu bigufi cyangwa ubushyuhe burenze urugero hamwe no gukingira imyaka-kurinda ibitekerezo byinjira (OVP) kugirango bikingire birenze urugero. Impande zo hejuru zunvikana hamwe na p-umuyoboro ucuramye MOSFET yemerera itumanaho ryiza ryumurongo wa LED kugabanywa kugeza kumurongo winjiza neza cyangwa kwinjirira nabi ntakintu cyangiritse. Iki nikintu cyihariye kiranga IC.
Kwishyira hamwe bigabanya BOM kuri High-Brightness LED Umushoferi hamwe ninjiza yagutse Urwego rwo kuzigama Umwanya nigiciro
