Part Number: LM2743
I am the 2018 NCG Yang. I want to consult you something about the IC recommendation (LM2743).
The case is my customer's power supply (2nd generation) for PCIe with requirements as below:
1. Input: 12V
2. Output: 3V3
3. Load Current: 12.5A max (Typ 10A)
4. low cost
For the 1st generation, customer uses LTC1778 controller + NMOS SI4392, and now they want to use TI's controller.
I used filter on TI.com to recommend LM2743, while I am not sure if it's a good choice. So I get two points to discuss with you as below:
1. It's a good choice to use LM2743 ?
2. Do you have some tips/procedures to share, about recommending TI solutions for customer's requirements? (usually I use filter on TI.com, while it provides many alternatives)
LM2743 would work for this application. Another option is TPS40303 or TPS40304. Ti.com is a good option to select parts.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
