1.General Description
The PN8326 consists of a high precision CC primary side controller and a power MOSFET, specifically designed for a highperformance low power LED lighting with minimal external components and duplex winding. The chip operates in primary-sidesensing and regulation, so opto-coupler and TL431 could be eliminated. The chip adopts a patent HV DMOS self-supply technology,so auxiliary winding and HV Start-up resistance could be eliminated. The chip offers complete protection coverage with automaticself-recovery feature including Cycle-by-Cycle current limiting protection (OCP) and feedback loop open protection (OLP), overtemperature protection (OTP) , Rcs open/short Protection and LED-open/short circuit protection etc. Internal HV Start-up circuit andthe chip's very low consumption help to meet high efficiency. In CC control, the current and output power setting can be adjustedexternally by the sense resistor Rcs at CS pin, and the chip can meet the requirement of wide-range line voltage certification.
