Output 23.6 V / 0.05 A
IC revisionC

Description

The TIDA-00486 TI Design uses Texas Instruments SimpleLink Wi-Fi CC3200 Internet-on-a-chip Wireless MCU module to create a data bridge between an RS-485 network and a Wi-Fi network. An ISO15 transceiver provides an isolated RS-485 interface with up to 2500 VRMS of isolation. The LM5160 Fly-Buck™ power supply provides both isolated and non-isolated 3.3 V outputs for the two portions of the circuit. The design can be powered with AC or DC power up to 30 VRMS or 48 V peakA version of this design with a non-isolated RS-485 interface is presented in TIDA-00485.
