So the bare minimum capacitor I need is 1. DOes anyone know anything more about this overcharging?

Bootstrap capacitor overcharging | Electronics Forum (Circuits, Projects and Microcontrollers)

Jul 31, 8. The low Vf is important from an efficiency standpoint.

This is important for your boost cap supply diode and your gate diode. It’s Vr is only 20v, so not useful for a boost cap charge diode over about 15v. Jul 31, 2.

Hi DK, I’m not implying that I can help, but you really should post a link when you refer to something that obviously has one the IR app note. Jul 31, 9.

Bootstrap capacitor overcharging

A 1N would be a better diode to use on rt98 gate, as it has a much d9t8 Vf than the 1N Posted by MaxHeadRoom in forum: Datasheets, Manuals or Parts. Yes, my password is: In this topic, in first message, DumbDummy77 used some values for Vf and Vls.


If somebody help me, I will be grateful. I tested a random 1N several years ago and created this plot to show Vf over a range of If: Jul 31, You May Also Like: Roff Well-Known Member Mar 2, If your MOSFETs have a very low gate charge, you might get away with it, but you have not provided any information about them.

No, create an account now. Welcome to our site! Media New media New comments Search media. So, I’ll use 33 Ohm tomorrow, and I’ll reduce. The IRFZ44 is fairly old.

I’m charging up the capacitor to 14V diode drop already accounted for and it must stay above 12V. Thanks for all helps.

But, while much of the focus has been turned to Android Dt89 and Google Glass and other software releases, there hasn’t been nearly as much press on Project Ara, and that’s just ridiculous.

Jul 31, 5. Jul 31, 3.

I check the boost supply to prove it is not starving out at minimum and maximum duty cycle. Jul 31, 6. Vf, Vls dtt98 Vmin aren’t clear. Quote of the day. Dknguyen, Onsemi has an application where they set the boost strap capacitor by p-p ripple voltage on the capacitor.
