Part Number: LM25149-Q1 Hi team,
I would like to control PFM/FPWM mode depends on the system operation mode.
I pull up PFM/SYNC pin to VDDA through 22kohm register for PFM operation,
and pull down to GND through transistor.
I concern pull VDDA to GND…

Could you please give me CISPR 25 test result of LM25149-Q1 with and without AEF?
I found conducted emission data in the datasheet, but I would like to see Radiated Emission…
Part Number: LM25149-Q1 Hello
We have designed our custom board with the schematic as per " Design 2 – High Efficiency 440-kHz Synchronous Buck Regulator" as shown in the datasheet and the BoM is also as mentioned in the datasheet. However…
Part Number: LM25149-Q1 Hi team,
1.The current limiting loop on the schematic diagram of the EVM uses an RC filter, but it is not included in the reference design of the Datasheet. The customer hopes to know the parameter selection calculation method…
Part Number: LM25149-Q1 Hi team,
What would be the maximum current LM25149-Q1 can output with Fsw = 2.2MHz (or close to 2MHz)?
Vin = battery level, nominal = 14V, max up to 18V functional.
Fsw = 2.2MHz.
Ta,max = 70C.
Can LM25149-Q1 support below application…
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.

Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Hi team,
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…
