you can go for their web site for data sheet.U are right.so many ICs avalable in the market.LIke TOREX.But main problem is that this type of ic s not avalable in india normaly.I got the circuit from a persion who bild this total diagram.this circuit efficency level more than 94%.very low...
hi do you have any boost converter circuit diagram.My requrement
voltage in min-3.8V to max 4.5V (4Amp)
out put min- 10.5 to max 10.8 (700 mA) 10 watt
if you have then please send me urgent. i need it dear
:grin:
OK Sneha.I got your point.The simplest way to transfar data throug GSM better you buy 2 nos of usb gsm modem.cost arount 3k.now enable two gsm sim for edge or UMTS (normaly known as 3G).now you can send every type of data every corner of world.I am also worked a power plant (JINDAL POWER).So...
first thing u confrm that sim 300 support EDGE or not.I dont have any idea about this sim300.we r using diffrent type gsm modem.I think u using usb stick for internet.It,s also a gsm modem.
i will send you the config but its not working without CISCO devices.I thing you must keep in your mind...
first you tell me wichi device you are using for sending data.if you useing any router with gsm modem moule then you need some config.I can send you the config if you r using cisco devices.else you can do the same thing using some third party software.
yes its possible from one server to another server using gsm.but if the data size is learge then UMTS is better option.bcoz it can provide upto 21mbps or higher bandwidth.
first thing you have to make ip base tunnel from your source to destination.

Its very usefull circut for making small timer range 1min to 30 mnts .It can oparate 1min to 180 mnts.jst change the C1 & VR1 value.
HI ALL its a very usefull circuit for those who r trying to make a high efficency boost converter.
The only problem that this IC not avalable every where.
Dear Tahmid,
Thnx for your reply.There are many curcuit avalable in website.But they all are using some specal chip base.Wich is not avalable in INDIA normaly.It,s very difficult to buy all those.But if we go for some genaral component like using MOSFET, IC Like 555
etc. then...
HI Thami.
I want 2 make a boost converter with more than 90% efficiency.Input Voltage 3.8 v to 4.6 v / 4 Amp.Output voltage need 10.5 to 11 v 800 mA. Please send me the diagram if you have.
:grin:
