Part Number: LM3409 Tool/software: Hi!
We have a design based on LM3409 IC. The original idea was to adjust the output current with a PWM signal on the EN pin.
After the first batch we started to test the circuit, but the currents were not close to…
Part Number: LM3409 Tool/software: Hello team,
I am wodering how much LED current does LM3409 can drive?
I understand LM3409 is controller (external FET), so it will depend on FET we use, but is it possible to drive 10A rated FET with LM3409?
Best Regards…
Part Number: LM3409 Tool/software: Hi TI team,
The part number of the LED driver is LM3409MYX/NOPB.
We observed a heating of more than 60°C while connecting the LED load. Also we observed slight heating even without connecting any load.
