Hello everyone

Do anyone have any idea to build a DC-to-DC flyback converter with desired output?
For example like the input is 6v, so output can be more or less than 6v by using PWM to control the duty cycle.
 

Hi,
If it's in such small voltage range, why use flyback, and not dedicated buck-boost converters. There are tons available, check those from Maxim, Dallas and Linear.

Hope this helps.

Mr Tahmid
so do u have any schematic to as a reference?
is it i use buck-boost converter, can have desired output??

thank you very much for reply me
 

There are many. Check website of Maxim and Linear Technology: **broken link removed**, Linear Technology - Linear Home Page

For reference:
Vin = 4 to 60
Vout = 3.3 to 20

Linear Technology - LT3433 - High Voltage Step-Up/Step-Down DC/DC Converter

This uses internal switches, ie, the power switch is integrated into the chip. If high power is required, just use the external switch chips.

Hope this helps.

Mr Tamid,
U suggest me this 1 is it nid to be programming 1?
 

Hi,
This is an IC, not a microcontroller, so it doesn't need to be programmed. It is built for the function, just plug it into the circuit and you have a running circuit.

Hope this helps.
