PN8360

PN8360 Chipown High Precision CC/CV Primary-Side Converter General Description The PN8360 consists of a high precision CC/CV primary side controller and a 650V power MOSFET, specifically designed for a high performance low power AC/DC charger and LED lighting with minimal external components. PN8360 operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated. PN8360 offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting protection (OCP), over voltage protection (OVP) and feedback loop open protection (OLP), over temperature protection (OTP) and short circuit protection etc. Internal HV Start-up circuit and the chip’s very low consumption help to meet the strict standby power standard. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rcs at CS pin. In CV control, PFM operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built-in cable drop compensation.
