Part Number: LM25149-Q1 Hello,
I'm trying to switch at a slower frequency with high attenuation. After using equations #26 in the data sheet, I was noticing that the capacitance values can get pretty high . Is there an upper limit on how big I can make…
Part Number: LM25149-Q1 Hi team,
Could you advise the tolerance of CNFG input?
I would like to calculate the resistor tolerance to connect to CNFG.

Could you advise if LM25149-Q1 power up to pre-biased output without abnormal voltage on output?
I concern "momentary drop of the car battery" condition, The shortest…
Part Number: LM25149-Q1 Hi team,
How is LM25149-Q1 output behaves if it changed from diode emulation mode to FPWM mode on the fly using PFM/SYNC pin control at light load (DCM) operation, or vice versa?
I would like to make sure OUT voltage is stable…

Hello,
I'm trying to replicate this WeBench circuit in PSpice, but am encountering errors. Here is the Webench circuit:
Here is the PSpice layout:
Here is the error when I try to run the simulation (N04654 is the wire…
Part Number: LM25149-Q1
Hello,
I'm pretty new to PSpice, but what I'm trying to do with the below circuit is run a line test that waits until the system has reached 6V, jumps to 17V quickly, and then measures how the system responds.
Here is…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Hello Team,
Thanks for your support.
In the previous thread, it is recommended that applying SYNC signal before LM25149 startup.
Q. Is it OK "VIN powers up => SYNC input => EN turns high"…
