LM3560: Maximum number of LED's which can be driven by FLASH_LED_OUTPUT_1

Atharva U

Part Number: LM3560

How many LED's LED1/LED2 pin can drive. I can't find data on maximum voltage output which can be raised by internal boost converter. Hence asking for this data.

I'm using 3.3v drop white LED's in series and curious on how many of them I can use.

Thanks

Hi Atharva,

Please refer to page4 6.1 of datasheet.

Thanks for the revert charles.

I did came across page 4 section6.1 but I couldn't understand the rating, and that's why I asked this question in the first place.

LM3560 has boost converter, right ?

so does it mean it can boost the output voltage to max 6 V?

Thanks

Hi Atharva,

The output voltage is limited typically 5V(5.075V maximum). 6V is the maximum stress. So the OVP will be triggered when the output voltage is beyond 5V.
