Power Integrations RDK-866 Reference Design Kit

Power Integrations RDK-866 Reference Design Kit is a non-isolated buck converter power supply with an input line Zero-Crossing Detection (ZCD) output signal. The LinkSwitch-TNZ IC controller powers the nominal output 5V, 500mA power supply. Simplicity and efficiency are achieved due to the high level of integration while still providing exceptional performance. The RDK-866 Reference Design Kit operates across an input range of 90VAC-300VAC and is intended for wireless (WiFi, NBIoT, etc.) and relay power.
