* General Descriptio
The PN8328 consists of a high precision CC primary side controller and a power MOSFET, specifically designed for a high performance low power LED lighting with minimal external components and duplex winding.
The chip operates in primary-side sensing 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 automatic self-recovery feature including Cycle-by-Cycle current limiting protection (OCP) and feedback loop open protection (OLP), over temperature regulation (OTC) , Rcs open/short Protection and LED-open/short circuit protection etc.
Internal HV Start-up circuit and the chip's very low consumption help to meet high efficiency. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rcs at CS pin.
