Description and Introduction

8A Active Bus Termination/ DDR Memory DC/DC Converter 28-HTSSOP -40 to 85 The TPS54872PWPRG4 is a synchronous buck converter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 17V  
- **Output Voltage Range:** 0.76V to 7V  
- **Output Current:** Up to 8A  
- **Switching Frequency:** 200kHz to 1.6MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** HTSSOP-20 (PowerPAD™)  

### **Descriptions:**  
The TPS54872PWPRG4 is a high-efficiency, synchronous step-down DC-DC converter with integrated MOSFETs. It is designed for high-performance power supply applications, providing precise voltage regulation with low output ripple.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Frequency:** Allows optimization for efficiency and size.  
- **Precision Reference:** ±1% voltage accuracy over temperature.  
- **Power Good Output:** Monitors output voltage status.  
- **Soft Start & Stop:** Prevents inrush current.  
- **Overcurrent & Overtemperature Protection:** Enhances reliability.  
- **Synchronous Rectification:** Improves efficiency.  
- **Low Quiescent Current:** Optimized for light-load efficiency.

Application Scenarios & Design Considerations

8A Active Bus Termination/ DDR Memory DC/DC Converter 28-HTSSOP -40 to 85

Alternative Part Number

  • TPS54872PWPR --: Same TPS54872 buck converter in the same HTSSOP-28 PowerPAD package, identical electrical specifications; the G4 suffix only denotes lead-free/RoHS green status, so this is a drop-in replacement.
  • TPS54873PWPR --: Sister device in the same TPS5487x family with the same pinout and package, offering a different switching frequency setting; usable as a close functional substitute with minor configuration changes.
  • TPS54620RHLR --: Comparable 6A synchronous step-down converter from TI's SWIFT family in a smaller VQFN package; requires layout adjustment but provides similar input range and current capability.
