Part Number: LM46002
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 Hello. Formula 22 in the LM46002 data sheet is yielding results that do not make sense. I am getting values much larger than expected. Can someone check this formula? It looks like there is a typo there.
Part Number: LM46002 Hi team,
As you can see in the following picture, there are two same PCBs, LM46002 in the second PCB may have some thing wrong. The Vcc has a step in the second PCB when starting up. If we put the second PCB in -40℃，the Vcc will…
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 Dear team,
Vin and BIAS are both input of internal LDO, why give the same 12V to Vin or BIAS, output of LDO Vcc is different? 7 out of 2 LM46002 are in this situation, they may be damaged while testing, but I want to know the theory…
Part Number: LM46002 I am using LM46002 as an inverter in order to get -12V output when Vinput = +12V. The output voltage is correctly regulated at light load condition or low loads, but when I connect 1A load the converter output (-12V) is unstable and…
Part Number: LM46002 Hi team,
Could you kindly advise for more detail of the OV detection function of LM46002 ?
Our customer is looking for the devices with OVP function.
Thank you and best regards,
Michiaki
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 Frank, thank you.
Excuse me of my persistence.
I read snva722b Application Report.
1) LM46002 can supply minus 15 V output, if input voltage is 15 V and more.
But the input voltage may be slightly less, than 15 V, for…
Part Number: LM46002 We are using a LM46002 regulator to provide an output voltage that can be selected between +12V or +24V from a +48VDC input voltage. The selection is done under microcontroller control using a transistor to switch in a parallel resistance…
