IRS29831 datasheet



The IRS29831 is an integrated LED driver control IC and power MOSFET designed to drive Flyback and Buck-Boost converter based LED drivers. The IRS29831 includes primary side power regulation allowing a low cost isolated or non-isolated LED driver to be implemented without the need for an opto-isolator for a fixed LED load.
