Part Number: LM25119
Dear Team,
The customer using LM25119 for 18V/120A application.
They have 2 board with the same schematic, but slightly different layout.
One board work properly till 100% load, but one of the board will unstable around 90A.
Do you…
Part Number: LM25119 Hi,
I have several problems in using LM25119 need help.
1.What is the maximum voltage of COMP pin? 2. What is the maximum design power of this IC? 3, how to deal with the actual uneven current of two output when used for interlacing…
Part Number: LM25119 hello,
LM25119
i m planning to design a converter with parameters below:
Vin: 28V Vout: 25V Iout: 25A (can be set by external sources to 20A or 15A or 10A)
with this controller and its application circuit. how can i add output current…
Part Number: LM25145
Hi
I am using this controller for my design, but I am confused about current limitations of 20A. How did you defined this current limit?
I am designing my converter having 30A load current. Isn't output current related to Mosfets…

Part Number: LM25119 Other Parts Discussed in Thread: LM5119 Hi,
Do we have some reference designs about LM25119 to do 4 phase interleaved buck? Thanks.
Part Number: LM25119 Hello.
I am having a coulpe of issues with the LM25119.
I am only using 1ch from the chip for now and have disabled CH2.
Running at 50khz Vin18V , Vout 12V. Max output current 25amps.
Issue 1 - I power up the reg with no load, and…
Part Number: LM25119 Other Parts Discussed in Thread: LM5119 Hi team,
as my customer use LM25119. they want to ask, if the circuit input power supply is 38V, then the SW pin voltage would be 38V + 3V=41V(caused by DV/Dt), the customer already implement…
Part Number: LM25119 Hi,
I have a problem with LM25119 chip. Output voltage is ~1V on each channel, assuming there should be 5V.
Vin is 24V. I measured VCC1 which is 7.5V. Voltage between VCC1 and HB is 6.47V, SS1 is 4.6V, FB1 is 0.8V, COMP1 is 1.08V…
