Part Number: LM25143-Q1 Other Parts Discussed in Thread: LM5143
Hello team,
we operate the LM5143 in single output(3.3V) 6-phase mode. How to the wire of the slave controllers?
This is the information provided in datasheet. How to provide 0, 60, 120 degree…
Hello Alex,
For an optimal effieicnt desgin, suggest going with the 2 types of FETs and not using all 4 of the same. The reason being is for a high step-down ratio the LS FET is on most of the period. This will incur the most I^2R losses and the HS FET…
Part Number: LM25143-Q1 Hello Texas Instruments,
Good Day!!!!!!!!!
In the datasheet we can't able to find the maximum channel current of LM25143-Q1. Just wanted to know what can be the maximum current of both channels(VOUT1 & VOUT2)
Thanks for…
Part Number: LM25143LM25143RHAR implemented as dual channel output voltages 3.3V (yellow) and 6.1V (blue). Monitor ripple on outputs using 100MHz oscope, noise < +/- 22mV, no spikes.
When using a 200MHz oscope, see occasional 100mV spikes on 6.1V…
Part Number: LM25143-Q1 Hi team,
Could you please advise how to configure LM25143-Q1 in standby mode?
I configure dual phase single 3.3V output in regular operating mode and plan to switch to standby mode
when my system need to save power.
I understand…

Part Number: LM25143-Q1 Hi Team,
May I know the VFB-REG voltage variation under -40oC to 85oC TJ & TA?
The data listed in the datasheet is based on 25oC TJ.
Or the VFB-REG range works for -40oC~150oC TJ?
Thank you.
Part Number: LM25143 Other Parts Discussed in Thread: LM5143 Hi Team,
Does LM25143 support 20V input and 20V output? Do we have support input48V/38V/28V and output 20V and support GaN solution?
Many thanks~
