Description and Introduction

4.5V To 14V Input Synchronous Buck Controller With 4-Bit Vid Interface And Power Good 16-VQFN -40 to 85 The TPS40197RGYR is a synchronous buck controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 18V  
- **Output Voltage Range:** 0.6V to 5.5V  
- **Switching Frequency:** Adjustable from 200kHz to 1MHz  
- **Maximum Output Current:** Supports high-current applications (external FETs required)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 20-pin VQFN (RGY)  

### **Descriptions:**  
The TPS40197RGYR is a non-isolated, synchronous buck DC-DC controller designed for high-efficiency power conversion. It supports a wide input voltage range and adjustable output voltage, making it suitable for various applications, including telecom, industrial, and computing systems.  

### **Features:**  
- **Adaptive On-Time Control:** Improves transient response  
- **Adjustable Soft-Start:** Prevents inrush current  
- **Power Good Indicator:** Monitors output voltage status  
- **Pre-Biased Output Startup:** Safe for pre-biased loads  
- **Programmable Frequency:** Allows optimization for efficiency or size  
- **Overcurrent and Overtemperature Protection:** Enhances system reliability  

This controller requires external MOSFETs and passive components to complete the power stage.
