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…
Part Number: LM25119 Hi team,
my customer use LM25119, but the two phase current is not balanced, please help.
Vin: 35V;
Vout: 21V Iout: 9A;
the difference of the two phase average current is about 640mA. how our part do the current balance function? …
Part Number: LM25122-Q1 Other Parts Discussed in Thread: LM5122 , LMC555 Hi Suppot members.
I have a 4-phase LM251122 application, which is Vin=25~33V, Vout=48.5V/22A. @235kHz, but still got some confusions.
1.when doing 4-phase operations, does it make any…

Hi,
From TI.com, can see the Iout(max) of LM25119 is 40A.
As I know, the current limitation is all about MOSFET and Inductor, am I right?
Here are the question:
1. How this 40A be defined? …
Part Number: LM25119 VIN: 24V
VOUT: 12V
IOUT: 30A
F:400KHZ
The interleaved two currents are uneven, one side 10A, the other side 20A.
The two parameters are exactly the same.

Part Number: LM25119 Hello!
I am currently designing a supercapacitor charger based on LM25119 with parameters as follows:
Input voltage: 24V
Frequency: 200kHz
Output: CC-CV, 30A, 5.3V
The supercapacitors are to be charged with a constant current with…
Part Number: LM25119 Hi,
Doing output short circuit condition, when shorted output 1, the output 2 will be protected as well, is this normal?
Thank you.
