Part Number: TIDA-01512 Hi TI team,
As far as the remote voltage sense signals of the controller(both A and B channels) is there any specific impedance requirement between traces or they can routed as normal differential signals? If any specific impedance…
Part Number: TIDA-01512 Other Parts Discussed in Thread: CSD95490Q5MC Hi TI team,
As per the reference design given for the LS2088A from TI, there are a lot of decaps placed on 1V rail and 1.2V. We are already having decaps for the LS2088A as it was…

Hi TI team,
While going through the layout guidelines it is mentioned that the CS pins must be routed as differential pair with the Vref trace. can you please let me know whether any specific impedance is required for this…
Hi Sai,
Transient data for TIDA-01512 can be seen on page 10 of the design report. You can switch to a 300nH inductor for the core rail of your design but it will cause larger overshoot during the 60A transients than the 150nH choke. If you go that…
Part Number: TIDA-01512 Other Parts Discussed in Thread: CSD95490Q5MC Hi TI team,
I am rightly working with LS2088A and I am taking the reference design from TI to generate the Core and DDR rails. I have a doubt regarding the LSET value resistor.…
Hey Sai,
Please see the attached files for TIDA-01512 . The XML file is for uploading and use in the Fusion GUI while the text file is for easier manipulation on your end if you need to put it into another system.
The 1.05V boot voltage for the core…
Part Number: TIDA-01512 Other Parts Discussed in Thread: TPS53681 Hi TI team,
I am presently implementing the multiphase reference design from TI in my LS2 based project. I have installed the GUI but I am not able to find out the PWM controller IC…
Part Number: TIDA-01512 Hi,
I am following the reference design provided from TI for the generation of core and DDR voltages of my LS2 design. In the reference design there is an inductor on the 12V rail before the current sensor resistor. The part…
Part Number: TPS53681 Other Parts Discussed in Thread: TIDA-01512
Hi,
I am currently working with the TPS53681 IC in a design related to LS2088A. I have got a reference design from TI website. Upon going through the datasheet of the PWM TPS53681 I…
Hello,
The bode plot you took is definitely a valid result even though Phase doesn't cross 0 degrees over the frequency range you measured. With 45 degrees of phase margin your design can be considered stable as well but should you need to push it higher…
