Hi,
I need a solution for DC-DC converter.
I need to charge 2 x AA batteries of 1.2V using this CKT.
Please suggest any compleet solution for my requirement.
Regards,
Krithik
Dear Jack,
Can you please see the attached CKT.
This is flyback topology.
Accoring ti that IC the operating frequency is 135KHz.
We are engineers. We dont do the things and designs without knowing the topology of SMPS.
Ok.
I Have own company named as Anvaya Designs in INDIA.
You can use this transformer design.
If you want any help feel free to ask.
And we can also support proto development. But for this we will charge for every design.
If you are interested please feel to contact me.Just give me the...
Hi,
Can you please send me the input and output power specifications and operating frequency.
Also let me know in which type of transformer you want to put in PCB.For 24W EE25 core transformer is preferable.
Just give me the details i will give you the solution for your design.
Hi,
Design with Zener for MCU Supply is correct and not preferable.
Because MCU having little bit tolerance +/-1% only.
But in now a days we cant believe the zeners. Regularly we can get 12.1V zener from market. But it will have the tolerance of minimum 5%.
And more over the zener tolerance...
Thanku thamid.
But i didnt find compleet solution in this pdf.
And also i dint understand the operation.what is the mean by carrier wave and what is the purpose of thia.
Please thamid help me.and give me the compleet solution including magnetics drawings.
Thanku Tahmid,
But i dont have knowledge about micro controllers.
If you have the complete working model solution please send me.
I have already viewed the file(Pure Sine wave inverter Based on SMPS) in your profile.
If possible please send me the details of your demo board.
Please share...
Please Give me the input specification i will give you the complete design.
What i mean to say that, Please tell me the input voltage.
If you need design for 48V to 48V why you need the design.
