RT8415数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The RT8415 is a two-stage LED driver controller with the 2^nd stage MOSFET integrated inside. It consists of a Boost controller on the first stage and a Buck converter on the second stage. By adapting two-stage topology, RT8415 is highly compatible with ET (Electronic Transformer) and performs extremely high Power Factor in specific MR16 / AR111 LED lighting applications.



The Boost converter on the first stage provides constant output voltage with well inductor current control. The Buck converter on the second stage provides constant LED output current by hysteretic peak current regulation.



The RT8415 is available in the SOP-8 (Exposed Pad) package.
