Hi Fang,
It looks like your VIN is not able to keep up, the yellow line continues to dip which implies your VIN might be current limiting.
Please try increasing your VIN current limit, or reducing the IOUT of the load.
Note that when VIN is close to VOUT…
Part Number: LM25145 Hello,
I would like to ask you about the pin connections of the LM25145. (Question 1) If I don't use the pins below, how should I connect them? 7pin: SYNCOUT 8pin: SYNCIN 10pin: PGOOD (Question 2) Can the following pins be connected…
Part Number: LM25145 Other Parts Discussed in Thread: LM25148 , LM5145 , LM5148 , LM5149 hi team,
is LM25145 stackable ?
if yes,
please provide reference schematic, I can't find in the datasheet
Part Number: LM25145 Hello,
Please tell me how to detect the dead time of LM25145. I have confirmed the following descriptions in the datasheet. (Question 1) Is dead time detected by HO pin and LO pin? (Question 2) If the above is YES, please tell us the specific…
Part Number: LM25145 Hello,
I would like to ask you a question about the LM25145. The condition of Tj at Irdson=200uA in the electrical characteristics is 25℃ as shown in the figure below. However, looking at the description in 8.3.10, it is 27°C. which…
Part Number: LM25145 Hello,
I would like to ask you a question about the LM25145. When does the 10uA hysteresis current flow in the EN circuit shown below? Is it when EN exceeds 1.2V?
Best regards,
Part Number: LM25145 Other Parts Discussed in Thread: LM61440 Hi,
I designed in the LM25145 using Power Designer. I need 12V input, 3.3V output and 4A. I copied the schematics almost exactly, except I used a 6.8uH vs the 6uH in the Power Designer and…
Part Number: LM25145
Hello,
I am an FAE for a distributor that handles TI products. The customer asked me about the LM25145. (Question 1) Is it possible to configure the HO pin and LO pin as shown below? Adding gate resistors and pull-down resistors *In the…
Part Number: LM25145 Other Parts Discussed in Thread: LM5145 , LM5146 Hi team,
I was wondering why we use LM5145EVM for LM25145 hardware development? What's the differences between LM25145 and LM5145?

hi team,
my customer use 18 LM25145 per board,
please help check the MOSFET thermal (maximum Ta=80C) and schematic,
you can take some days to review, it's alright.
