Other Parts Discussed in Thread: LM3429
I need an immediate help in solving the issue with LM3429 for my design. The design details are
Vin : 10-15 VDC
ILED: 0.45A (typ)
Rlim - 0.075 ohm / 0.082ohm
DMN6040SK3-13 MOSFET and 27uH Inductor.
I'm facing an issue with instability in the output current of the driver and the result might damage the LED load since the current varies from 0.45A to 1.2A . During this issue, all the components seem to be in controlled temperature. I'm sharing the video captured of the MOSFET drain pin during the issue. I need quick response as our Production is planned for next week.
I'll share the schematics, gerber and design if you need them in solving the issue.
Thanks in advance.
