Hi Ben,
Attached is a presentation for overall 12V hot swap design. The TPS24742 includes ORing as well, but the hot swap portion will be the same.
So for 12V, 20A, see slide 9 in particular. Something like CSD17573 or CSD17570 could be a good choice…
Hi Simon,
For reference, the password for the tool can be found on the "intro" tab. It is "TPS2470X" and you can unlock the tool from the "Review" tab on the top of the page.
It took me a bit but I found the problem with the formula.
The equation…
Hi Karlis,
1. Hot swap design is meant to provide protection in case of fault cases. For example, that SOA calculation is used to ensure the MOSFET will not fail if the load draws too much current (such as if if there is a short circuit)
So indeed…
Patrick,
TI has a number of hotswap ICs that will handle 12v/15A. The TPS24700/01, TPS24710/11, TPS24720 can do this and have EVMs build for 25A applications that are easily scaled as you need. Please see www.ti.com/hotswap for selection and design…
Hi Ales,
When there is that much current being turned on/off, it is good practice to include a TVS diode on the input and a schottky diode on the output. You can check out the presentation below, slide 5 for information. These protection devices help…
Hi Feng,
I didn't want to overload you with too much information so I trimmed the presentation to include just the power supply section. The full presentation is attached below. In addition you may want to read the TI Designs TIDEP0041 and TIDEP0026…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
