Part Number: LM25143 Other Parts Discussed in Thread: PMP31202 Please let me know two points below about the CVCC connection method.
①The data sheet described that VCC-PGND1 and VCC-PGND2 are connected via capacitors.
Does this mean that two capacitors…
Part Number: LM25143-Q1 Other Parts Discussed in Thread: LM5143 dear
customer use LM25143-Q1,and want to design 100A circuit,but it only shows 50A in datasheet ,is it use 2pcs LM25143-Q1 to push 100A?thanks in advance
Part Number: LM25143-Q1 Hi team,
What is the Iq if configurate 25143 as two phase single output?
VOUT1=VOUT2=3.3V, DEMB=GND, MODE=VDDA
VOUT1 and VOUT2 are both enabled. I see in datasheet we only have Iq data in one enabled channel.
Thanks!
Part Number: LM25143 Hi, I have a question about the LM25143 Current Sensing implementation on the data sheet versus the example design given in LM5143Q1-EVM-2100 schematic.
In the EVM schematic, the current sense lines have an extra resistor and capacitor…
Part Number: LM25143 Hi
My customer says that the LM25143 is not working. Can I get a review of schematic and quickstart design tool? If you let me know your email address, I will send it to you. Please review it.
Thanks
Part Number: LM25143 Hi
My customer is reviewing LM25143 as a replacement for MAX1858(MAXIM). In MAX1858, there is a phenomenon that the frequency skips when sync off.
Is there a phenomenon that LM25143 is also skipped?
Thanks
Part Number: LM25143-Q1 Hi team,
How to calculate or derive input impedance of a LM25143-Q1 circuit? It is used to design the input filter before the power supply.
In the below app note: The Middlebrook’s extra element theorem (paper [2]), explains that…
Part Number: LM25143-Q1 Other Parts Discussed in Thread: LM25143 Hi team,
Is it possible to operate LM25143 with 3 phase and have one of the secondary IC’s output separated?
We want independent control to have 2 output with same voltage level Is…
