Part Number: LM3492
Hi,
a customer has the following issue:
"We currently have a problem with a LED driver. We have several identical circuits with the attached schematic. Unfortunately only one of them runs as expected, the others get extremely hot but don't work. Now we don't know if we have a soldering problem or if the dimensioning of the circuit is so at the edge that it's a gamble.
The LED strings consist of 4 and 6 white LEDs with 2.9V - 4.1V flux voltage.
Can you review the schematic attached?"
Thank you,
Franz
