Part Number: LM3409 Other Parts Discussed in Thread: TPS92692-Q1 , TPS92691-Q1 Hello to all,
is there a new possibility to get an online (or download) design tool for designing LED-Drivers, as it was on the old webbench?
I have to do a design for a LED…
Part Number: LM3409HV Hi,
I am looking for a table to calculate the LM3409HV at 48 V input voltage. I have the spreadsheet with the two off timers, but it seems that it gives wrong results when using only the standard circuit with one off timer and optional…
Have you looked into doing shunt fet dimming? for high PWM dimming frequencies you will likely need to do that in order to get good linearity.
Here is some high level training of LED drivers.

Part Number: LM3409EVAL Other Parts Discussed in Thread: LM3409 For schematic design of LM3409, such as PDF document design, if the input is 24V and the output is 5V, how should the corresponding parameters be designed? Does VTURN-ON need to be configured…
Part Number: LM3409 Dear All: According to the Spec, the Input is Maxim voltage is 75V, The actual input voltage is 75V, so it won't be damaged, right.(We can make sure the input voltage don't more than 75V, DC power supply output). What is the…
Part Number: LM3409-Q1 Other Parts Discussed in Thread: LM3409 Hello,
The LM3409-Q1 datasheet (SNVS602L) section 8.3.4 gives a minimum ripple current requirement in order to achieve reliable current regulation:

Part Number: LM3409 Datasheet did not mention it nor denying it, so I'd figure ask here.
I wanted to use LM3409 to drive 2 LEDs strings in Parallel, each consist 2 LEDs in series. This is because Vin is only 12V. Can LM3409 do this without any problem…
