Lighting

 

Lighting over Ethernet (LoE) in Industrial and Commercial applications need specialized power conversion, power management and EMI/ESD suppression.  At present time, new system designs are being adopted in this new and quickly expanding application area.  Lighting power requirements can be addressed with existing and upcoming industry PoE standards.  PoE solutions for lighting applications cover existing requirements and new standards such as IEEE 802.3bt with products that can support loads up to and above 60 watts.  In addition to PoE controllers, EMI/ESD suppression fill complete power management needs for lighting systems and applications.

 

+ PoE PD Controllers  

 

Applications requiring PoE typically need high efficiency power conversion, small PCB area and reduced component count. Kinetic Technologies offers a broad portfolio of product solutions which integrate the PD physical interface and DC/DC controller functions into a single package. Supporting solutions from a few watts up to the maximum allowed, Kinetic Technologies provides high efficiency power solutions for nearly every PoE PD application.

 

  • The AS11xx family of parts support single output isolated or non-isolated solutions for IEEE802.3af (Type 1) and IEEE802.3at (Type 1 and Type 2) PDs or higher power levels using custom programmed PSEs or by implementing the LLDP to enable 4-pair power delivery on the Ethernet cable.
  • The AS18xx family of parts support single and multi-output isolated solutions for IEEE802.3af (Type 1) and IEEE802.3at (Type 1 and Type 2) PDs or higher power levels using custom programmed PSEs or by implementing 4-pair power delivery. The AS18xx family, in addition to integrating the PD physical interface and DC/DC controller functions, adds synchronous rectifier control and integrated digital signal isolation thereby eliminating the need for opto-couplers. The multi-output versions support up to three additional outputs, each of which may be individually sequenced. All products include input and output over-current protection, output over-voltage protection, and over-temperature protection.
  • The AS18xx family has full command/control and monitoring capability available through the integrated I2C bus, which allows management of the power processing functions such as on/off control, voltage margining, sequencing of outputs, fault and alarm monitoring, and even input voltage and current.

+ EMI/ESD Protection  

 

Industrial lighting PoE Ethernet ports can benefit from ESD and Common Mode EMI suppression IC used to improve EMC performance in Ethernet applications.  The AS1602 helps eliminate EMC compliance challenges by providing consistent EMC performance and improvements utilizing silicon based technology as opposed to passive technologies.  The AS1602 enables system designers to comply with:

 

  • CISPR22 and FCC Part 15, Class B requirements for Radiated and Conducted Emissions.
  • IEC 61000-4-3/6 requirements for Radiated and Conducted Immunity, Level 3 or higher.
  • IEC 61000-4-2 ESD (Air Discharge) of ±25kV.
  • IEC 61000-4-2 ESD (Contact Discharge) of ±12kV.
  • Cable Discharge Event (CDE) of ±12kV.
