Ibiranga
1.Yujuje ibyangombwa byo gukoresha imodoka
2.AEC-Q100 Yujuje ibisubizo bikurikira:
- Ubushyuhe bwibikoresho Icyiciro cya 1: –40 ° C kugeza 125 ° C.
Ubushyuhe bwo Gukora Ibidukikije
- Igikoresho HBM ESD Itondekanya Urwego 2
- Igikoresho CDM ESD Itondekanya Urwego C4B
3.Ibikoresho byinjiza: 4 V - 40 V (45 V Abs. Mak.)
4.Umuvuduko w'amashanyarazi: 4 V - 75 V (80 V Abs. Mak.)
5.Fixed-Frequency Current-Mode Igenzura Na
Indishyi Zishyizwe hamwe
6.Ibice bibiri byateganijwe, Ibisohoka-Ibisohoka
na Umuyoboro uhoraho wa buri muyoboro
7.Icyerekezo Cyerekezo Cyerekezo:
- 150-mV cyangwa 300-mV Umuvuduko ukabije (EEPROM
Ihitamo)
- ± 6-mV Offset (Kugera hafi 4% cyangwa 2%
LED Ibiriho)
8.Ibisohoka Umuvuduko Wumuvuduko, Umuvuduko wimbere
Reba: 2.2 V ± 5%

Ibisobanuro
Umuryango wa TPS9260x-Q1 wibikoresho ni umuyoboro umwe hamwe nuyoboro-ibiri-ndende-ya-LED
umushoferi.Hamwe no kurinda no kwisuzumisha byuzuye, uyu muryango wibikoresho byeguriwe kandi bikwiranye no kumurika ibinyabiziga imbere.Intandaro ya buri shoferi wigenga ni impinga-yuburyo-bwo kuzamura igenzura.Buri mucungamutungo afite ibitekerezo bibiri byigenga byisubiramo, ibyagezweho-byisubiramo hamwe na high-current-sensing shunt na voltage-reaction loop hamwe numuyoboro wo hanze-utandukanya.Igenzura ritanga umusaruro uhoraho wa voltage cyangwa aconstant isohoka.Umutwaro uhujwe ugena niba igikoresho kigenga ibyasohotse bihoraho (niba umuzunguruko ugeze kumurongo wambere mbere ya voltage set-point) cyangwa guhora bisohora voltage (niba umuzunguruko ugeze kuri voltage set point yageze kubanza, kurugero, mugukingura -imiterere yimiterere) .Buri mugenzuzi ashyigikira topologiya zose zisanzwe nkaboost, kuzamura-bateri, SEPIC, cyangwa kuguruka. umuzenguruko kuri GND kugirango urinde uruziga.
