Description
Power Integrations RDK-877 Reference Design Kit
Power Integrations RDK-877 Reference Design Kit is an isolated flyback converter power supply designed to provide a nominal output voltage of 12V at 0.5A load. The RDK-877 kit operates from a wide input voltage range of 90VAC to 305VAC with an isolated zero-crossing detection (ZCD) signal. The LinkSwitch-TNZ IC controller powers the 6W power supply. The Power Integrations RDK-877 Reference Design Kit is intended for home appliance and industrial power applications.
