PM8803
High-efficiency, IEEE 802.3at compliant integrated PoE-PD interface and PWM controller, HTSSOP20, STM, RoHS

The PM8803 integrates a standard compliant Power over Ethernet (PoE) interface and a current mode PWM controller to simplify the design of the power supply sections of all powered devices. The PoE/PoE+ interface incorporates all the functions required by the IEEE 802.3at including detection, classification, undervoltage lockout (UVLO) and in-rush current limitation.

Features:

  • IEEE 802.3at compliant PD interface
  • Works with power supplied from Ethernet LAN cables or from local auxiliary sources
  • Successful IEEE802.3at Layer1 classification indicator
  • Integrated 100 V, 0. 45 Ohm, 1 A hot-swap MOSFET
  • Accurate 140 mA typ. inrush current level
  • Programmable classification current
  • Programmable DC current limit up to 1 A
  • Integrated high-voltage startup bias regulator
  • Thermal shutdown protection
  • Current mode pulse width modulator
  • Programmable oscillator frequency
  • 80% maximum duty cycle with internal slope compensation
  • Support for flyback, forward, forward active clamp, flyback with synchronous rectification
