Part Number: LM25148-Q1 Hello!
I would like to double check if this part can be used in applications where output specs is something like 5V, 25A. Is it necessary to use dual-phase mode in that case? If yes, why?
I assume since it's just a controller…
Part Number: LM25148-Q1 Hello Team,
I have question about DEM <-> FPWM.
Can my customer change between DEM mode and FPWM during operation by making low or high PFM/SYNC pin by TR?
Can the PFM/SYNC be pulled up by 10kohm to VDDA when controlled high…

Hi team,
Our customer is using attached quickstart calculator to calculate the power dissipation of LM25148-Q1. From the calculator Efficiency is calculated as 89.1% and total Pd is cal…
Part Number: LM25148-Q1 Hello Orlando,
To our question shown in the link below, you answered as follows.
"Yes, the primary phase is the phase that controls hiccup. The secondary phase has hiccup purposely disabled, and won't hiccup independent of…
Part Number: LM25148-Q1 Hi team,
my customer is looking into LM25148-Q1 in single phase configuration to regulate a 3V3 rail from a 12 V car battery. Targeted output current is ~16 A.
The question cam up:
What is the max power MOSFETs gate charge the controller…
Part Number: LM25148-Q1 Hello support team,
Please tell me about the operation when BOOT UVLO is detected. (V BOOT-SW drops to 2.5V)
What if the VIN is low and V BOOT-SW does not recover to 2.7V?
Thanks,

I have question about LM25148-Q1 vs LM25149-Q1.
Q. Are these difference only without AFE(LM25148-Q1) and with AEF(LM25149-Q1)?
Q. For dual-phase operation, can we use LM25149…
