Part Number: LM25148
Hi Sir,
For the design condition: 12V-in, 12-Vout, 15A-Iout.
Does the LM25148 can support the duty cycle up to 99~100%?
If it can not, please advise the correct solution. Thanks!
Part Number: LM25148 Tool/software: Initially design this device for up to a 12A load. But having issues starting up the regulator with a light load.
I need a reliable start up with a low power load of 30-40 mA. Is that possible? I can start up with…

My customer wants to know if our device can support the application below.
Application:
12V to 3.3V
maximum output current 30A(1us) 20A(100us)
typical current 15A
Fs 400kHz
The load…
Part Number: LM25148-Q1 Hi Team,
I'd like to know how to calculate the minimum inductance value of a buck inductor.
I understand that Equation 9 in the data sheet is a recommended inductance value, and not the minimum value that will not cause subharmonic…
Part Number: LM25148-Q1 Hi,
Does RT of this device have a limitation in the minimum value?
If RT = 8k ohm, What is the switching frequency?
Best Regards, Taki
Part Number: LM25148 Other Parts Discussed in Thread: LM5148 I am developing a power converter based on the LM25148. I made a post here two weeks ago about stubborn instability. That thread found I had not followed all layout guidelines for the chip, so…
Part Number: LM25148 Hi team
I want to know the detail between standby current and sleep current of LM25148. Test condition of standby current is 0.5V<Ven<1, this would mean device isn't active and output is 0V. Test condition of sleep current is 1.03V…
Part Number: LM25148 I've been in these forums recently to stabilize a LM25148 converter . The problem was identified as noise and fixed by slightly slowing down the high side gate drive signal. The Converter works fine at its designed output voltage…
Part Number: LM25148 Other Parts Discussed in Thread: INA280 I am developing a power converter based on the LM25148. My first design was not stable and I could not diagnose the problem so I backed up to the typical design #2 in the datasheet. I recreated…
