If i wanted a Vout of say 20 Volts instead dayasheet the 10 what would I need to change for this to occur. Quote of the day.

Sep 27, 9. In the case of a buck, it’s max Vin, and min Vout and max Iload.

Step Down Switching Regulator

The data sheet only provides the details of the chip it self. Hello, I want ot design a xatasheet converter with the following specifications: Sep 27, 3. Step-down switching regulator 12v to 3. Current limit from data sheet http: For a better experience, please enable JavaScript in your browser before proceeding. Sep 27, 7.


I’ll see if I can find it. High voltage 50v step down regulator Posted by MattP in forum: Yes, my password is: And what about C value? But I’ve seen it on the boards here and much more simple than the inductor. datsheet

To participate you need to register. How would I know the peak current which this is designed.? Plus, you always have to use the worst case values. Your name or email address: I don’t have the formula for the cap on me. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at So you need to change R1 to change the 10v output.

They are designed for that chip alone, not a generic buck converter. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Sep 7, 2, Boolean Identities The main identities associated with Boolean algebra are presented and discussed in detail.


How the output voltage is calculated? Thank you Smanches, Welcome to our site! L and C values. Sep 26, 18 0. Just saying hello Started by MichaelaJoy Yesterday at 6: Sep 27, 8.

Maybe C is not necessary L and the load make a filter? Media New media New comments Search media. For 20v output you would have 1. If I apply to my application I find: Sep 27, 2.
