PN8355 Chipown High Precision CC/CV Primary-Side Converter General Description The PN8355 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. PN8355 operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated. PN8355 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.
