PN8355 - Chipown

PN8355 High Precision CC/CV Primary-Side Converter

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.
