Part Number: LM5149-Q1 Tool/software: Dear TI experts,
My customer drew 1st schematic using LM5149-Q1. Could you review the schematic below?
Best regards,
Chase
Part Number: LM5149-Q1 Tool/software: Hi team,
Does the noise suppression of DRSS exceed AEF(Active EMI Filter)? Which one is more effective for EMI countermeasures?
Best regards,
Shunsuke Yamamoto
Part Number: LM5149-Q1 Other Parts Discussed in Thread: LM5149 , , LM25148-Q1 Tool/software: In a forum post on a related topic, Orlando Murray stated the the PSPICE model for the LM5149 does not support simulating this part in dual-phase mode. Do you…
Part Number: LM5149 Tool/software: Hello everyone,
I’m trying to simulate the LM5149 in PSpice for TI 2024. I’ve downloaded the LM5149-Q1 PSPICE Transient Model from the TI website and followed the provided steps.
After loading the file,…
Part Number: LM5149 Tool/software: Hello,
We have designed with 5 LM5149 DC-DC on board, and we are experiencing overheating under no load conditions. Any idea what could cause that? Also active current is 190mA peer 3 active DC-DCs at 24V input voltage…
Part Number: LM5149 Tool/software: Hello experts,
I'm measuring Bode Plot and have some questions.
1. The y-axis of the phase is different, what is the difference?
2. Is the Bode plot of the Quick start calculator simulated based on an open loop? …
Part Number: LM5149-Q1 Other Parts Discussed in Thread: LM5149 Tool/software: Hi team,
My customer selects LM5149-Q1 in their 48V ACU project. They want to know when Vin=48V, Vout=14V, Load=100uA, what's the total current consumed by LM5149-Q1 itself…
No luck yet with that. But I was just looking at your files again. The rev 2 design looks a lot more stable, but you mention the duty cycle is getting clamped. This could be the peak current limit engaging.The quickstart file shows 9mΩ for the current…
Part Number: LM5149-Q1EVM-400 Other Parts Discussed in Thread: LM5149 Tool/software: Hi experts,
I did a lab test about LM5149 Start-up characteristic.
However, unlike the results in the datasheet, Iout increases sharply, causing an inrush current.
…
Part Number: LM5149-Q1 Tool/software: Dear TI experts,
My customer checks the specification of LM5149-Q1 for automotive application.
The input is 48V, and output is 12V.
And my customer is worried about EMC and surge/reverse voltage.
Do you have any…
