Idatha ye-CN5711 yePD
Inkcazelo ngokubanzi:
Inkcazo ngokubanzi: I-CN5711 ngummiselo wangoku wesekethe edibeneyo esebenza kwi-input voltagI-e ye-2.8V ukuya kwi-6V, imveliso ephuma rhoqo yangoku inokusekwa ukuya kwi-1.5A kunye ne-resistor yangaphandle. I-CN5711 ilungele ukuqhuba ii-LEDs. […] I-CN5711 yamkela ummiselo wobushushu endaweni yomsebenzi wokukhusela ubushushu, ummiselo wobushushu unokwenza ukuba i-LED ivulwe ngokuqhubekayo kwimeko yobushushu obuphezulu okanye ivolthi ephezulu.tage drop. […]
Usetyenziso: Isibane esikhanyayo, umqhubi we-LED oqaqambileyo, izibane ze-LED, izibane eziNgxamisekileyo kunye nezibane […]
Iimbonakalo: Umsebenzi weVoltage Uluhlu: 2.8V ukuya 6V, On-chip Power MOSFET, Low Dropout Voltage: 0.37V @ 1.5A, i-LED yangoku ukuya kuthi ga kwi-1.5A, Ukuchaneka kwangoku: ± 5%, uLawulo lobushushu beChip, phezu koKhuseleko lwangoku lwe-LED […] Kukho iindlela ezi-3 zokusebenza kule IC:
- Ngomqondiso we-PWM osetyenziswe ngokuthe ngqo kwiphini ye-CE, ukuphindaphinda kwesiginali ye-PWM kufuneka ibe ngaphantsi kwe-2KHz.
- Ngomqondiso wengqiqo osetyenziswa kwisango le-NMOS (Umfanekiso 4)
- Nge potentiometer (Umfanekiso 5)

Isabelo sePin 
Umzobo 3. I-CN5711 iqhuba ii-LED kwiParallel 
Umzobo 4 Umqondiso wengqiqo kwi-Dim LED
Indlela yoku-3: I-potentiometer isetyenziselwa ukunciphisa i-LED njengoko kubonisiwe kuMfanekiso 5.
Umzobo 5 I-Potentiometer yokunciphisa i-LED
Inyathelo lesi-2: Qhuba iLed ngeYakhelwe kwiPotentiometer
Ndiyathemba ukuba i-wiring icacile kwiifoto kunye nevidiyo.
V1 >> blue >> unikezelo lwamandla +
CE >> blue >> unikezelo lwamandla +
G >> ngwevu >> umhlaba
LED >> brown >> kwakhokelela +
Ukunika amandla isekethe ndisebenzise umbane ophantsi (owenziwe nge-atx yamandla endala kunye ne-ZK-4KX buck boost converter) . Ndibeka i-voltage ukuya ku-4.2v ukulinganisa ibhetri ye-lithium yeseli enye.
Njengoko sinokubona kwividiyo, amandla esekethe ukusuka kwi-30mA ukuya ngaphezulu kwe-200mA

I-Adjustable current ngokusebenzisa i-resistor ehlengahlengiswayo.
Nceda usebenzise isikrudrayiva esifanelekileyo ukujikelezisa ngobunono nangokucothayo
Inyathelo 3: Qhuba iLed ngeMicrocontroller
Ukulawula isiphaluka nge-microcontroller vele udibanise i-pin ye-CE kwi-PWM pin ye-microcontroller.
V1 >> blue >> unikezelo lwamandla +
CE >> purple >> pwm pin
G >> ngwevu >> umhlaba
LED >> brown >> kwakhokelela +
Ukumisela umjikelo womsebenzi ukuya ku-0 (0%) i-LED iya kucima. Ukumisela umjikelo womsebenzi ukuya kuma-255 (100%) i-LED iya kukhanyisa ngamandla amakhulu. Ngemigca embalwa yekhowudi sinokuhlengahlengisa ukukhanya kwe-LED.
Kweli candelo unokukhuphela ikhowudi yovavanyo ye-Arduino, Esp32 kunye ne-AtTiny85.
Ikhowudi yovavanyo yeArduino:
#define pinLed 3
#define led off 0
#define led On 250 //255 yeyona pwm ixabiso eliphezulu
ixabiso langaphakathi = 0; //pwm ixabiso
useto olungenanto () {
i-pinLed, OUTPUT; //setto il pin pwm yiza uscita
}
iluphu engenanto () {
//qhwanyaza
I-analog Bhala(ikhonkile, ikhokelwa); // Cima i-lead
ukulibaziseka (1000);
// Linda okwesibini
i-analog Bhala(ikhonkile, ikhokelwa); // Vula i-LED
ukulibaziseka (1000);
// Linda okwesibini
I-analog Bhala(ikhonkile, ikhokelwa); //...
ukulibaziseka (1000);
i-analog Bhala(ikhonkile, ikhokelwa);
ukulibaziseka (1000);
//dimm
kuba (ixabiso = ledOn; ixabiso > ledOff; ixabiso -) {// nciphisa ukukhanya ngokunciphisa "ixabiso"
I-analog Bhala(i-pinLed, ixabiso);
ukulibaziseka (20);
}
kuba (ixabiso = ledOff; ixabiso < ledOn; ixabiso ++) {//ukwandisa ukukhanya ngokwandisa "ixabiso"
I-analog Bhala(i-pinLed, ixabiso);
ukulibaziseka (20);
}
}

Inyathelo 4: Inguqulelo kaDiy
Ndenze inguqulelo ye-diy yemodyuli ngokulandela isekethe yedatha yedatha.
Ndisebenzise i50k potentiometer nangona idataeti ithi "ixabiso eliphezulu le-R-ISET yi-30K ohm".
Njengoko ubona isekethe ayicocekanga kakhulu…
Ngendisebenzise i-SOP8 ukuya kwi-DIP8 pcb okanye i-SOP8 ukuya kwi-DIP8 iadaptha yesekethe entle ngakumbi!
Ndiyathemba ukwabelana ngegerber file kungekudala ukuba ungasebenzisa.
Inyathelo lesi-5: Ndizakukubona kungekudala!
Nceda undishiye izimvo zakho ngezimvo kwaye uxele iimpazamo zobugcisa kunye negrama!
Ndixhase kunye neeprojekthi zam kule khonkco https://allmylinks.com/dariocose
Umsebenzi omhle!
Ndiyibonile impazamo enye yegrama yobugcisa enokubangela ukubhideka. Ekupheleni kwenyathelo lesi-2 uthi:
"Njengoko sibona kwividiyo, amandla esekethe ukusuka kwi-30mAh ukuya ngaphezulu kwe-200mAh"
Oko kufanele ukuthi "30 mA ukuya 200 mA."
Igama elithi mAh lithetha "milliamps amaxesha iiyure kwaye lumlinganiselo wamandla, hayi umlinganiselo wangoku. Ishumi elinesihlanu leemiliyoniamps iiyure ezi-2 okanye i-5 milliamps iiyure 6 zombini 30 mAh.
Ubhalwe kakuhle uyafundisa uyakwazi!
Enkosi!
Ulungile! Enkosi ngengcebiso yakho!
Ndilungisa kwangoko!
