China electronic component PN8036 Non-isolated PFM converters IC, Find details about China electronic component, LED driver from electronic component PN8036 Non-isolated PFM converters IC
The PN8315 consists of a high precision quasi-resonant mode CC primary side controller and a power MOSFET, specifically designed for a high performance low power LED lighting with minimal external components and single-inductance.
The chip adopts buck topology and work in quasi-resonant mode; 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, 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.
