Part Number: TPS53125 Hi there:
Greeting~
I’d like to check customer design for using TPS53125 to output 1.05V/11A & 1.0V/11A those two (for Skylake-S platform), but I couldn’t find the similar design in Webench.
I’d like to ask whether it has…

I have found that the voltage supplied by the customer may vary ±3VDC. This puts the TPS51285 and TPS53125 parts out of consideration. I have looked at the alternative, TPS43351-Q1. It has a input range of up 40VDC. As I have mentioned before…
Other Parts Discussed in Thread: TPS53015 , TPS54429 , TPS54525 , TPS53125 Hello,
My coustomer searching solution to implement 'remote sense' at the devices TPS53015,TPS54429,TPS54525.
If they can use remote sense function, let me know how to use…
Hi Fred,
Your calculation is right, the cap will add a zero, and a pole at much higher frequencies.
The frequency of the zero can be derived from (Rtop * C) , and the frequency of the Pole is driven from ((Rtop || Rbottom) * C)
If you want to understand…
Part Number: TPS54325 Hi,
Recently, I have read an application report, named "D-CAP2TM Frequency Response Model based on frequency domain analysis of Fixed On-Time with Bottom Detection having Ripple Injection"(SLVA546). In this report, it writes "The…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
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…
