The TPS23770PWPR from Texas Instruments is a versatile integrated circuit designed for Power over Ethernet (PoE) Powered Device (PD) applications. It combines the functionality of a PoE front-end with a primary-side DC/DC PWM controller, enabling designers to create robust PoE-PD solutions with a reduced external component count.
Key features include a complete IEEE 802.3af PoE interface, a 100V, 0.6 Ohm internal pass MOSFET, and standard and legacy undervoltage lockout (UVLO) choices. It also incorporates a fixed 140 mA inrush current limit for safe power-up sequences. The device supports primary-side DC/DC converter control with current mode control, isolated and non-isolated topologies, and programmable operating frequency.
This controller is housed in an industry-standard 20-lead HTSSOP package and operates within an industrial temperature range of -40°C to 85°C. Its integrated PoE functions, including detection, classification, UVLO, and inrush control, simplify design for applications such as wireless access points, VoIP phones, and security cameras.
