Description and Introduction

3A Sink/Source DDR Termination Regulator w/ VTTREF Buffered Reference for DDR2, DDR3, DDR3L and DDR4 10-VSON -40 to 85 The TPS51200DRCT is a synchronous buck controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information:

### **Descriptions:**  
- The TPS51200DRCT is a high-efficiency synchronous buck controller designed for low-voltage, high-current applications.  
- It supports DDR memory power supply applications, including DDR2, DDR3, DDR3L, and DDR4.  
- The device integrates a high-side and low-side MOSFET driver to optimize power efficiency.  

### **Features:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable (supports DDR memory voltages such as 1.5V, 1.35V, 1.2V, and 1.05V)  
- **Switching Frequency:** 300kHz to 1.2MHz (adjustable)  
- **Integrated MOSFET Drivers:** Supports N-channel MOSFETs  
- **DDR Memory Support:** Compatible with DDR2, DDR3, DDR3L, and DDR4  
- **Power Good Indicator:** Provides a power-OK signal  
- **Soft-Start Function:** Reduces inrush current  
- **Overcurrent Protection (OCP):** Prevents damage from excessive current  
- **Thermal Shutdown:** Protects against overheating  
- **Package:** 10-pin VSON (DRC)  

### **Applications:**  
- DDR memory power supplies (DDR2, DDR3, DDR3L, DDR4)  
- Notebook computers  
- Embedded systems  
- Low-voltage, high-current power supplies  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

3A Sink/Source DDR Termination Regulator w/ VTTREF Buffered Reference for DDR2, DDR3, DDR3L and DDR4 10-VSON -40 to 85

Alternative Part Number

  • LP2998MRX/NOPB --: DDR termination regulator with similar sink/source tracking function and comparable current rating, commonly used as a TPS51200 alternative.
  • ISL6537CRZ --: Integrated DDR memory power supply controller providing VTT termination and VDDQ regulation, functionally similar to the TPS51200.
  • RT9045GSP --: DDR bus termination regulator offering sink/source VTT tracking output, suitable as a cross-vendor replacement for DDR termination applications.
  • ISL6228IRZ --: DDR memory termination regulator with integrated VTT tracking, functionally similar to the TPS51200 sink/source tracking regulator.
  • LP2998MRX --: DDR termination regulator with VTT and VREF outputs, similar sink/source tracking function though from a different TI series.
