Hello,
I have a question regarding the usage of the LED Driver for High Power LEDs
At the moment I am using MAX16834 LED Driver https://www.maximintegrated.com/en/...rs/MAX16834.html/design-development/tb-tabs-2 to drive this LED https://www.osram.com/ecat/OSRAM OS...im_web_catalog_103489/prd_pim_device_8160601/
The LED is 23V and 10A - 230W
When I drive this LED in a Boost configuration everything works fine, I can turn ON, OFF and dim LED without any issues
Now I need to change configuration to Buck-Boost and drive it from 24V
When I placed all components and modified board to this configuration LED Driver itself got burned when the voltage reaches around 22V on the input
Is there any fundamental issues driving LED in a Buck-Boost mode having around 1V headroom from input to output?
Is there anything obvious from the datasheet that I am missing?
Best regards,
Tim
