Texas Instruments TPS23758 | Demoboard TPS232758EVM-080

IEEE 802.3at PoE PD with no-opto sync flyback DC-DC controller

Details

TopologieSperrwandler
Eingangsspannung37-57 V
Ausgang 15 V / 2.3 A

Beschreibung

The TPS23758 device combines a Power over Ethernet (PoE) powered device (PD) interface, a 150-V switching power FET, and a current-mode DC-DC controller optimized for flyback topology. The high level of integration along with primary side regulation (PSR), spread spectrum frequency dithering (SSFD), and advanced startup makes the TPS23758 an ideal solution for size-constrained applications. The PoE implementation supports the IEEE 802.3at standard as a 13-W, Type 1 PD.

Eigenschaften

  • IEEE802.3at Type 1 compliant PoE PD
  • Class 0 5-V and 2.3-A primary side regulated CCM flyback
  • Advanced startup
  • Programmable slew rate and frequency dithering for EMI reduction
  • Primary-side adapter priority control

Typische Anwendungen

  • IP cameras, Access points, IP phones, Wireless LAN- wireless access points
  • Point-of-sale, Barcode readers
