Part Number: LM46002 Hi,
the Output voltage of the LM4002 is set to +5V. But sometimes in the first 100ms after powering up the output voltage rises up to 11V. Then it slowly comes back to 5V and then it works fine.
The capacitor Cff which is parallel…
Part Number: LM46002 Tool/software: WEBENCH® Design Tools I request free sample from ti store,found LM46002 footprint is dull-red,is it normal colour ? is it have silver footprint?
Hello,
There is a specific P-SPICE model for the LM46002 IBB topology. You can find this in the models table.
Please let me know if you have any additional questions or if anything is unclear.
Best Regards,

Hi,
In the Buck circuit, if an overvoltage/overcurrent/thermal problem happens and LM46002 is damaged, what the two MOSs looks like? Short or open? And what's the output looks like?
For these two MOSs, I can only find Rds…
Part Number: LM46002 Other Parts Discussed in Thread: LM73606 , LM73605 Is it possible to parallelise two or more LM46002 for more output current? If yes how?
Part Number: LM46002 Design:
24V In
-17V Out
0.5A max
At what load should I expect the part to drop into PFM operation? How is this affected by the switching frequency set by RT?
What amount of output capacitance should I have for -17V Out…

Hi,
When you power up VIN, could you check the SW node waveform and see if there is any switching action in there while your EN pin is low?
Is there a way to isolate the output of LM46002 from other circuitry to prevent any back feeding from other…
Part Number: LM46002 Dear team,
When customers were testing, 2 of their PCBs couldn't start up. The Vcc pin was 2.7V which just meet the UVLO of Vcc. If the LM46002 was blown by a heat air gun, the IC could start up. The schematic is as followed.
