RT8495规格书详情
描述 Description
The RT8495 is a dimmable two-stage LED driver controller with the 2nd 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, the RT8495 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 RT8495 is available in the WDFN-10L 3x3 package.
