Other Parts Discussed in Thread: TPS51315 Hello,
Our implementation of TPS51315 doesn't power up reliably unless we hold EN_PSV low while the input rails Vin and V5IN and V5FLT are ramping.
- If we hold EN_PSV low for 100ms until the other rails…
Other Parts Discussed in Thread: TPS59116 , TPS51315 Hi,
I am not quite sure about the ESR requirements on Cout for the TPS51315/TPS59116. In D-CAP Mode, to keep the loop stable, the ESR or Cout or both should be large enough. Howvere, to get the required…

I have a high-volume customer who is using the TPS51315 in two different scenarios:
REQ2: 4.5-5.5Vin, 1.2Vout @ 7.7A
REQ4: 4.5-5.5Vin, 1.5Vout @ 10A
In order to make things simpler for procurement…
Hi all,
Recently, I have used a few TI Power IC in one of my project. I would like to ask you guys to help to review my schematic and layout of those power circuits. I have upload the schematics and layouts and attached it to this post. Please download…
I am currently using a TPS 51315 which is stepping down 7V to 1.2V with a maximum output current of 7.5A. The power supply is driving 32 FPGA's which require over 200 ceramic decoupling capacitors along with several tantalum capacitors. I know that…
Keven,
There are a variety of PMICs and power solutions which have been used for Netra, some of them include battery backed RTC.
Here are some potential solutions. Note, not all include a RTC.

Hi Krishna,
It sounds good. TPS51315 and TPS53353 are very similar controllers. Both are D-CAP mode control with fast transient response and no loop compensation. They also integrated MOSFET. This will make your design simple. I attached an excel file…
