TPS23770 - Integrated 100-V IEEE 802.3af PD and DC/DC Controller

Description

The TPS23750 integrates the functionality of the TPS2375 with a primary-side dc/dc PWM controller.

The designer can create a front-end solution for PoE-PD applications with minimum external components.

Features

  • s derived from the TPS2375.
  • 100 V, 0.6 Ω Internal Pass MOSFET.
  • Standard and Legacy UVLO Choices.
  • Fixed 140 mA Inrush Limit.
  • Primary Side DC/DC Converter Control.
  • Minimum External Component Count.
  • Current Mode Control.
  • Isolated and Non-Isolated Topologies.
  • Programmable Operating Frequency.
  • Current Sense Leading-edge Blanking.
  • 50% Duty Cycle Limiting.
  • Voltage Output Error Amplifier.
  • Internal.
