Part Number: LM3691 Tool/software: Hi Team,
Customer is asking the absolute maximum rating for switching node.
They assume the a bsolute spec is only DC rating, The AC (less than 10ns) Absolute Maximum Ratings for the SW pin (while switching) would be:…
Part Number: LM3691 Hi,
for one of my projects, I am using a Load switch for 3.3 after that LM3691 regulator to stepdown to 1.8V. due to more rise time, the complete 3.3V generates after 1.8 V at the output, as the enable is tied to Vin of regulator, once…
Part Number: LM3691 Hi,
My customer has ensured that this requirement is met during power-up:
Datasheet page 16: " 8.4.2 Shutdown Mode .... EN pin must be set low to turn off the LM3691 during system power up and undervoltage conditions when the supply…
Part Number: LM3691 Hi,
My customer see an issue with slow ramping Vin (20 sec from 0V to 5V).
I request your advice and reproduction of this test on a 3V3 part to see if you also can find it.
More details can be provided by me offline via email to the…
Part Number: LM3691 Hello,
I need to create a 0.8V output. Can I use feedback resistors on the LM3691TL-0.75 device to generate the desired output voltage?

I found this image about the layout of the LM3691.
Are the "KEY" description colored in the opposite way?
Thanks
Hi
We found a unknown operation at start up. (Vin ramp up very slowly.)
Yellow: Vin, Blue:Vout, Pink: Iin
There is two step operation. It looks that different current limit works at each step.
(MODE pin is connected to Vin directly.)
Is it in ECO mode…
