Part Number: LM5149-Q1EVM-400
Hello,
Devi kit: LM5149-Q1EVM-400 changed Top and Bottom mosfets I have startup issue with no load: Vin 34V Vout should be 12V, but than turn on power supply Output is 4.96V Iload 0A,
if I connect 90mA load to output, it become…
Oh good.
For the layout, go with a solid unbroken GND plane on layer 2 directly below the powr stage (see the EVM as a reference). Also, an AGND island is useful as well. Copy the EVM layout much as possible here.

Tim
Part Number: LM5149-Q1 Tool/software: Hi all,
My customer considers to use LM5149QRGYRQ1 with the following configuration. Sometimes the output is not output. The waveform is below.
VIN(VBAT)=28V
Vout=7V
Output
Not output
In many cases, this phenomenon…

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-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-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…
