TPS23770PWP Description

Short technical summary and product information.

The Texas Instruments TPS23770PWP is an integrated circuit designed for Power over Ethernet (PoE) Powered Device (PD) applications. It combines a 100-V IEEE 802.3af compliant PoE interface with a primary-side DC/DC PWM controller, minimizing external component count for front-end solutions.

 

Key electrical specifications include a maximum input voltage of 67V and a PD power level of 13W. The device features a typical inrush current limit of 0.14A and a minimum PoE current limit of 405mA. The internal pass MOSFET is rated for 100V with 0.6Ω resistance. It operates within an industrial temperature range of -40°C to 85°C.

 

The TPS23770PWP supports both isolated and non-isolated topologies and offers features like current mode control, programmable operating frequency, and a voltage output error amplifier. It is housed in a 20-lead HTSSOP package suitable for surface mounting.

 

This controller is ideal for applications such as wireless access points, VoIP phones, and security cameras that require PoE connectivity.
