Description and Introduction

High Efficiency PoE Interface and DC/DC Controller 20-TSSOP -40 to 125 The TPS23757PWR is a Power over Ethernet (PoE) powered device (PD) interface and DC/DC converter controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range (VIN):** 36V to 57V (PoE compliant)  
- **Output Voltage (VOUT):** Adjustable via external components  
- **Maximum Output Current:** Depends on external MOSFET and inductor selection  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 14-pin TSSOP (PWR)  
- **Compliance:** IEEE 802.3at (PoE+) standard  
- **Integrated Features:**  
  - Hot-swap MOSFET controller  
  - PWM controller for DC/DC conversion  
  - Programmable current limit  
  - Under-voltage lockout (UVLO)  
  - Thermal shutdown protection  

### **Descriptions:**  
The TPS23757PWR integrates a PD interface and a DC/DC controller for PoE applications. It supports high-power PoE+ (up to 25.5W) and simplifies the design of powered devices such as IP cameras, wireless access points, and VoIP phones.  

### **Features:**  
- **IEEE 802.3at (PoE+) Compliant**  
- **Integrated 0.25Ω Hot-Swap MOSFET**  
- **Supports High-Efficiency Flyback or Forward Converters**  
- **Programmable Inrush Current Limit**  
- **Adaptive On-Time Control for Fast Transient Response**  
- **Wide Input Voltage Range (36V to 57V)**  
- **Thermal Shutdown Protection**  
- **Available in a 14-Pin TSSOP Package**  

This device is designed for reliable power delivery in PoE applications while minimizing external component count.
