Hi Daniel,
When Vo rises to 1.7V there is no switching at all. The voltage on SW is perfectly constant and is equal to 1.7V too.
It kind of look like the combination of some diodes threshold voltage inside the converter. I expect this could be a reason…
Part Number: LM46002 Other Parts Discussed in Thread: LM46001 , LM46000 , LM5117 , LM5116 , LM5145 Is there a similar Part with almost the same parameters (Frequency, RDSon..) and package like LM46002 but with adjustable current limit?
Best regar…
Part Number: LM46002 Dear TI-Engineers
we intend to drive 15 LEDs at approx 49V, 0.6A from an 60V power supply using the LM46002 as a CC source because of it's excellent efficiency and price. Instead of feeding back the divided output voltage, we measure…
Part Number: LM46002 Tool/software: WEBENCH® Design Tools Hello,
I have tried to design a buck using the LM46002 and with the following
Vin = 21V to 42VDC
Vout = 13.8V, Iout =1A
Webench gave me an error that the design would be unstable and did…
Part Number: LM46002-Q1
Hi Team, The datasheet shows the following however I coudn't find detail defference between LM46002-Q1 and LM46002A-Q1. >The LM46002A-Q1 version is optimized for PFM operation and recommended for new designs. Could you tell me…
Part Number: LM46002-Q1
CIrcuit is based off a web bench design. I added the voltage divider for the enable pin. I can see the ~3.2 volts on the VCC pin but 0V on the output. The enable pin gets above 1.2V. Red layout is the top, blue is the bottom…
Part Number: LM46002
Hi Sir, Currently we Interested TI Positive/Negative Power Rail reference design PMP9379 because PMP9379 uses external circuitry to ensure that the +/-15V output track each other, i.e. the output voltage above and below 0V are well…
Part Number: LM46002 Hello,
I have got a query about LM46002.
The question is about an issue we are seeing in a LM46002 we use as -15V Buck regulator very similar to the figure 1. in - www.tij.co.jp/.../snva722b.pdf)
We are generating +/-15V with…
