Started by fastline Yesterday at 8: Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Sep 27, 9. Current limit from data sheet http: Step-down switching regulator 12v to 3.

Chippie 78w40 Jul 8, L and C values.

The data sheet only provides the details of the chip it 78w40. Hello, I want ot design a buck converter with the following specifications: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at They are designed for that chip alone, not a generic buck converter.


Sep 27, 8. Feb 11, 5, 1, I found this attached file on the 78S40 datasheet.

Welcome to our site! If I apply to my application I find: How the output voltage is calculated? In the case of a buck, it’s max Vin, and min Vout and max Iload. Vital knowledge for any designer.

How would I know the peak current which this is designed.? The formulas from that datasheet make some assumptions about the circuit.

Build Raspberry Pi Controllers: Try National Semiconductors simple switcher series. I don’t have the formula for the cap on me.

High voltage 50v step down darasheet Posted by MattP in forum: Maybe C is not necessary L and the load make a filter? For a better experience, please enable JavaScript in your browser before proceeding.

Sep 27, 7. Do you already have an account? The L and C values are determined by Ton and Toff, which is a function of the switcher frequency, in this case the frequency is 1MHz. No, create an account now.

Plus, you always have to use the worst case values. As BRE has suggested have a look at simple switchers, or look at the 78S40 data sheet Although I’m not sure if it will switch that high Thank you Smanches, Just saying hello Started by MichaelaJoy Yesterday at 6: If i datashfet a Vout of 7s840 20 Volts instead of the 10 what would I need to change for this to occur.
