hello everyone,

I searched on internet for a boost converter which converts from 40~60 to 60 V.
I found an application note SLVA372C for TI talking about the calculaction of boost converter.
I was very easy without tell me what IC I should use for my application.

Please If anyone has any application note or ready information to use it in my project, please tell me.

thank you

 

60V at what current?

 

60 V at 1A current maximum

Hello Bordodynov
yes I see , it's a good circuit , but the maximum Vin voltage in datasheet is 16V only , is this realized ??
another question about the input , what is the maximum input voltage ? 60 V?

thank you

 

Haven't you noticed D1 Zener diode in Bordodynov diagram ?

 

The supply voltage is limited by Zener diode chip. In this case, a parametric voltage stabilizer. It is necessary to monitor the power that is dissipated zener diode and a resistor. I think that the resistance of the resistor must be done 5.6kOhm. I used this converter for 50-90 volts, only without zener, power supply I had 11 volts.

 

@Jony130 yes I see that, thank you.
@Bordodynov it's a good design and I like it but the problem with LT1935 which isn't in our country.

I want to try another option in the figure below, and listen to your opinions.


F= 47.3KHz .
Feedback ratio : 1:12


If it's a good circuit, I continue with it , and if it's not , I will switch to the first design.

thank you
