Hi team,
Do we have this analysis available in PSpice model? Customer said it will report error when applying this. What is the variety of the distribution?
Thanks!

When DIM= 3.3v, the oscilloscope is used to measure the signals of SW, CS and A respectively：

Hi,
I'm considering using the LM3402 device.
The specifications are as follows.
The LED voltage is assumed to be 17.4V.
Is it possible to output such a high voltage?
(specification)
VIN:24V
VLED:17.4V (VF=2.9V*6)
ILED:0.5A
Best regards…
I was using LM3402 to drive one 1W high power LED of 530nm, set current sensing resistor as 0.56 Ohm. Input a PWM dimming signal of 80kHz. Found some wave strange as attached using current probe on scope.
That seems current wave performed…
Hi,
I need to know the recommend PWM frequency range for brightness control of LM3402. Also will it be sufficient if we apply a 3.3V logic PWM signal?
Thanks

Hello,
We plan to use the LM3402 and noticed that:
- the RON shall be tight to VIN through a resistor to set the ON time
- the absolute maximum voltage on RON input with respect to GND is 7V
- our VIN is higher than 7V
There is no…
We are using the LM3402 in a public transportation application where there are several (up to 40) LED strips, for internal lighting. We have been using them since 2012. However, recently the customer has decided to add tire inflation…
