OCP8155

OCP8155 „ Description OCP8155 is a high precision constant current LED driver IC with an integrating 650V power MOSFET, designed for offline flyback constant current LED lighting within 18W output power, and suitable for universal input voltage from 85VAC to 265VAC. IC adopts DIP-8L package. OCP8155 utilizes primary-side feedback technology to achieve excellent line regulation and load regulation without TL431, optical coupling and feedback circuit, greatly saving the system cost and size. OCP8155 is provided with perfect protection functions. The chip detects the VCC pin for over-voltage detection, and once detecting an over-voltage signal, the chip enters a “Hiccups” mode to limit output power. Meanwhile the chip also includes LED open/short circuit protection, FB short circuit protection, under-voltage lockout and over-temperature protection functions to guarantee the entire system work safely and stably in harsh working environment.
