PN8316 Internal HV Start-up Non-isolated quasi-resonant mode Converter for LED Driver
Description
PN8316 includes a high-precision quasi-resonant constant current controller and power MOSFET, dedicated to high reliability,high efficiency, single inductor,very thin peripheral components
Non-isolated low-and medium-power LED lighting. PN8316 adopts BUCK circuit architecture and operates in critical conduction mode; the patented technology of fast DMOS self-power supply can be used to achieve high-speed DMOS self-power supply.
Save high voltage start-up resistance. The chip provides an extremely comprehensive self-recovery protection function,including cycle-by-cycle overcurrent protection,open environmental protection, over-temperature adjustment,CS resistance
Open short circuit protection and LED open short circuit protection, etc. Built-in high voltage start-up circuit and very low chip power consumption contribute to higher work efficiency. In constant current mode, the current and
The output power can be adjusted by the Rs resistor of the CS pin.
