LM3410: Suggestion for alternate device

Part Number: LM3410
Other Parts Discussed in Thread: TPS61165, TPS61169

I am currently using LM3410XSD (WSON | 6pin) to drive the backlight of a display on a controller. Unfortunately, the display is changing to one that requires 26V nominally at 60mA. The LM3410 max output voltage is 24V.  Is there a footprint-compatible LED driver that would work in place of LM3410 so that I do not have to change the PCB?  The requirements are as follows: 

  • Similar footprint as LM3410XSD
  • Input voltage: 3.3V
  • Output voltage: 30V max
  • Current: 60mA max

It looks like TPS61165 is the closest match, but it seems that this device can't support 30V out with 3.3V in--is that true? If so, are there any other options to consider?

Thanks,

Brian Angiel

    Hi Brian,
    TPS61165 can actually support with 3.3V input voltage and 30V output voltage, 60mA. But the package is not compatible with LM3410. I have checked all one channel LED driver, TPS61169 is very similar with LM3410, both have 5 pins , but TPS61169 is alttle smaller than LM3410.
