Texas Instruments LM5160 | Demoboard TIDA-00485

Non-Isolated RS-485 to Wi-Fi Bridge with 24 VAC Power Reference Design

Overview

TopologyFlyBuck (Double Buck)
Input voltage18-30 V
Output 13.3 V
IC revisionE3

Description

The TIDA-00485 TI Design uses Texas Instruments Simple Link 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 SN65HVD72 transceiver provides the RS-485 Interface with 12 kV of ESD protection, and additional protection is provided on board. The design can be powered with AC or DC power up to 30 V RMS or 48 V peak.A version of this design with an isolated RS-485 interface is presented in TIDA-00486.

Features

  • Add Wi-Fi® connectivity to an RS-485 network quickly and simply
  • CC3200 Application Processor Provides Adaptability to Customer Communication Protocol
  • Wide Input Voltage Range of 18V to 30V AC, 12V to 48V DC

Typical applications

  • HVAC
  • Thermostats
  • Building Automation
  • Compressors
