Product Description

The NCN5120 is the first IC from ON Semiconductor"s family of KNX transceivers, handling the transmission and reception of data on the bus. It integrates a 20 V regulator and two high efficient DC-DC converters generating a fixed 3.3 V and a selectable 3.3 to 21 V regulated voltage from the bus with 100 mA drive capability each. This transceiver is ideal for high power applications and has been designed to reduce the bill of materials while supporting safe and reliable coupling to the bus thanks to features such as selectable current slope, bus voltage and temperature monitoring.
