Internal HV Start-up Non-isolated quasi-resonant mode Converter for LED Driver
1,General Description
The PN8316 consists of a high precision quasi-resonant mode CC primary side controller and a power MOSFET, specifically designedfor a high performance low power LED lighting with minimal external components and single-inductance. The chip adopts bucktopology and work in quasi-resonant mode; The chip adopts a patent HV DMOS self-supply technology, so auxiliary winding and HVStart-up resistance could be eliminated. The chip offers complete protection coverage with automatic self-recovery feature includingCycle-by-Cycle current limiting protection (OCP) and feedback loop open protection (OLP) , over temperature regulation,Rcsopen/short Protection and LED-open/short circuit protection etc. Internal HV Start-up circuit and the chip's very low consumption helpto meet high efficiency. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rcs at CSpin.
