Part Number: LM27403 Other Parts Discussed in Thread: CSD17573Q5B , , CSD17309Q3 , TPS40425 Hi Teams, In WEBENCH@ POWER DESIGNER, I select LM27403 (buck controller with discrete NMOSs) in DC/DC Power Designs. TPS40425 is a single phase controller combined…
Part Number: LM27403 Hi,
As the LM27403 circuit, current-sense differential pair should be routing as the same.
But at TI reference PCB design, Rset is put close to LM27403, not close to inductor as Rcs.
Can you double check it and give your…
Part Number: LM27403 Hi,
Test the tracking function of LM27403 to measure the following waveforms
Vin 12V, Vo set to 5V, load: 2A Startup time Sample 2 -> Sample 1 -> Sample 3
Take Sample 1 as the master, Sample 2 (3.3V), and Sample 3 (2.5V) as…
Part Number: LM27403 I'm seeing instability in my LM27403 design at colder temperatures. It appears that this comes from the compensation loop filter component selection. 90% of the units with this regulator are fine over the operating ambient temp range…
Part Number: LM27403 Hi Team,
At present, customers use this product for low voltage and high current applications, but this product will be very close to the fixture. Since IC is a heating element, customers will worry about the accuracy of the fixture…
Part Number: LM27403 Hello,
I am experiencing some on-time jitter on the switching-node output of my LM27403 circuit. I can provide all component values if needed, however I have observed the same node on the LM27403EVM and the percentage of jitter…
Part Number: LM27403 Form my test by LM27403 EVM and my PCBA, find out different date code had different Accurate, How to solve this Issue?
Test condition: Vin = 12V, Vo = 5V, Io = 12A and target Vout +/- 1%.
Date code: 7CAK5NU / Full load = 5.008V…
Part Number: LM27403
During the warehousing inspection (10 pcs from 3000 PCs), we found that there was a hole on the chip surface. The electrical test was passed, but there were many small holes after…
Part Number: LM27403 Trying to figure out whats causing a weird 10ms shutdown of the buck when load crosses 10A or so. Buck works fine with loads under 10A, but as soon as load exceeds that it shutdowns for 10ms exactly, then restarts.
I doubt Overcurrent…
