Description and Introduction

Single Phase, D-CAP+? Mode Step-Down Controller for IMVP6.5? CPU/GPU Vcore 32-VQFN -10 to 105 The TPS51611RHBR is a synchronous buck controller from Texas Instruments. Here are its key specifications, descriptions, and features:

### **Manufacturer:** Texas Instruments (TEXAS)  
### **Part Number:** TPS51611RHBR  

### **Description:**  
The TPS51611RHBR is a high-performance, single-phase synchronous buck controller designed for voltage regulator modules (VRMs) and point-of-load (POL) applications. It supports Intel VR12/IMVP7 specifications and provides precise voltage regulation for processors and other low-voltage, high-current loads.

### **Key Features:**  
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** 0.3V to 1.52V (adjustable)  
- **Switching Frequency:** 300kHz to 1MHz (programmable)  
- **Efficiency Optimization:** Adaptive on-time control with D-CAP™ architecture  
- **Current Sensing:** Lossless inductor DCR sensing or resistor sensing  
- **Protection Features:**  
  - Overcurrent protection (OCP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
  - Thermal shutdown  
- **Intel VR12/IMVP7 Compliance:** Supports dynamic VID (voltage identification) adjustments  
- **Package:** 32-pin VQFN (RHBR)  

### **Applications:**  
- Notebook/desktop CPU/GPU power supplies  
- Server and telecom point-of-load regulators  
- High-performance embedded systems  

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