Part Number: LM5012 Tool/software: As the title states, what happens to the LM5012 if the input voltage drops below the set output voltage? Does it pass through the voltage? Say for example the voltage output is set to 12V, and then the input drops to…
Part Number: LM5012-Q1 Tool/software: Hello
our customer is asking for the input current of the EN/UVLO pin not mentioned in the datasheet.
My understanding: its leakage of the comparator only.
please provide some data.
best regards
Martin
Hi Lei,
1. The load is powered by the output cap. This could happen only under low load conditions.
2. It is not with additional heatsink. It is just measured on the LM5013 EVM.
Thanks,
Nitya
Part Number: LM5012 Other Parts Discussed in Thread: LM5164 Tool/software: Dear Sir We replaced your LM5164 with a LM5012 (purchased from Mouser). Our input voltage is 75V DC. The LM5164 works flawlessly, however the LM5012 fails (when we enable it , it…
Part Number: LM5012-Q1 Tool/software:
Hi to TI support team,
i did this design, which works well now but with some emc problems.
The emc test engineer recommends, to populate a 2.2nF capacitor parallel to R21 (RT/SYNC) resistor.
He said, this improves…
Hi Nobert,
I would check the feedback voltage along with switch node in both fail and pass devices to check if the feedback voltage is as expected. If the injected signal is as expected, then it is LM5012 issue else we need to check injected ripple components…
Part Number: LM5012-Q1 Other Parts Discussed in Thread: LM5012 Tool/software: Dear TI experts,
My customer tests LM5012-Q1 on their own PCB, and there is a problem. Plase see the schematic below first ;
- They use PoE power (52V) for VIN. and it is…
Part Number: LM5012-Q1 Tool/software: Hi to all,
i finished my design with the LM5012-Q (Vin: 19.2V to 57.6V, Vout: 18V 12W). Circuit works fine after some capacitor improvement.
The issue now is, that EMC Test EN61000-6-3 E Field SAC 3m failed at 120MHz…

Part Number: LM5012-Q1 Other Parts Discussed in Thread: LM74700-Q1 , LM5012 Tool/software: Hello,
We have used LM5012-Q1 in our design. the input is 24V and we expect 12V at the output but we get 12.55V !! here is the circuit:
I checked the values for…
