Baterie tigara electronica cu TPS43000 de la TI

Salutare,

 

Sunt incepator in ale electronicii si vreau sa solicit ajutorul expertilor.

Mai jos avem schema tipica pentru TPS43000 (boost converter) pe care as dori sa o modific astfel:

tensiune de alimentare:7.4V (2 x accu 3.7v 2400ma) sau daca se poate 1 accu 3.7v(de preferat)

Iesire variabila:3.5v-6v(modificata printr-un potentiometru),Putere:12w

Curent iesire:2.5 - 3 A

 

Ce modificari se pot aduce schemei pt a obtine caracteristicile de mai sus ?

 

Ps:dimensiunile montajului trebuie sa fie cat mai mici posibil.

Iesirea se face pe un vaporizator (bobina de nichelina) 1,5-3 ohm rezistenta.

Frecventa cat mai mare posibil.

Multumesc anticipat

Incarcarea acumulatorilor cu Li nu se face asa,la intamplare...daca insisti sa-i incarci asa,sa faci rost de :nr de tel de la Salvare,nr unui zugrav bun,nr unui magazin de vopsele .O sa ai nevoie, ca sa vezi ce fain explodeaza accu pe Li.

Sant 'tz' integrate specializate care numai incarcarea accu pe Li stiu;de ce nu folosesti unul? (cu preturi de la 5 la 40 lei ,incomparabil mai ieftin decat numai zugravirea camerei).

montajul nu serveşte la încărcarea acumulatorilor,eu folosesc accu cu protectie si încărcător dedicat.

 

Acest montaj intenţionez sa il folosesc pt alimentarea rezistentei atomizorului.

Tensiune variabila 3-6 volţi,3 aperi

 

Robeert: linkurile cu firme se trimit pe MP, nu in public deoarece se considera reclama. Multumesc pentru intelegere.

"Acest montaj intenţionez sa il folosesc pt alimentarea rezistentei atomizorului.Tensiune variabila 3-6 volţi,3 aperi"Corect , am inteles asta , numai ca asa vei arde ... nichelina.Dece nu faci un stabilizator simplu 3V/2A?Oricum tigara , din portabila , devine ... stationara. :rade: Presupun ca esti un fumator inrait care vrea sa treaca de specifiucatia tehnica a fabricantului tigarii si sa ... pufaie continuu.In manual e specificat un "fum" la cateva minute , tocmai pentru a nu mentine nichelina permanent incandescenta.Dar asta'i alta ... poveste.

Folosesc mai multe tipuri de vaporizatore (atomizoare) care au rezistente diferite,In functie de voltajul aplicat gustul lichidului este diferit.La 3v cantitatea de vapori este mai mica gustul fiind mai intens iar la 5v este invers.Da,intradevar doresc sa am un voltaj stabilizat intre 3 si 6 volti,3 amperi,si 12-15 watiAm sa citez din specificatiile unei tigari ideale(X) dar pe care nu mi-o pot permite :"On/Off ModeYou can put the X in standby mode so it will not turn on the atomizer when the button is pressed.This safety feature prevents the atomizer from turning on while it's in your pocket or bag and it prevents any settings from getting changed without you knowing.16 Second CutoffIf the button is held down for 16 seconds or longer, the X will shut itself off until the button is released.If you forget to turn it off before storing it in your pocket or bag, this protects you and prevents the device from activating. Short Circuit/Atomizer ProtectionThis protects the X against shorted atomizers/cartomizers.If this error occurs the X will alert you by displaying E1 on the digital display.Fix: Remove the atomizer or cartomizer and replace with a different one. Reverse Battery ProtectionProtects against reverse battery installation.

Eu cand da frigul iarna renunt la tigarile normale(nu fumez in casa iar afara in frig nu stau pt o tigara nici daca ma premiaza producatorii de tigari) si trec la electronica care o folosesc de vreo 3 ani , primul an si jumatate exclusiv electronica.Cel mai greu pt mine e revenirea primavara la tigarile obisnuite , posibil la primavara sa nici nu mai revin total , mai ales acum cand au aparut modele mai performante de electronica ( acum am acumulator de 1100mAh , rezervor de 2,2ml cu atomizator de 1,8ohm ce se schimba cu doar 15 ron) Pachetul de tigari e in borseta , mai trag cate una la o cafea cand nu am electronica la mine , dar cam in scarba , m-am obisnuit deja cu gustul electronicii.
