Description and Introduction

LOW PIN COUNT SYNCHRONOUS BUCK CONTROLLER The TPS40190DRCR is a synchronous buck controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.7V to 5.5V  
- **Switching Frequency:** 200kHz to 1MHz (adjustable)  
- **Maximum Output Current:** Up to 20A (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-VSON (3mm x 3mm)  

### **Descriptions:**  
The TPS40190DRCR is a high-performance, synchronous buck controller designed for high-current, low-voltage applications. It supports wide input voltage ranges and provides precise output voltage regulation. The device integrates MOSFET drivers and features adaptive dead-time control for improved efficiency.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 28V input.  
- **Adjustable Output Voltage:** Configurable from 0.7V to 5.5V.  
- **Programmable Switching Frequency:** 200kHz to 1MHz.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Adaptive Dead-Time Control:** Enhances efficiency.  
- **Pre-Biased Output Startup:** Prevents negative current flow.  
- **Overcurrent and Overtemperature Protection:** Ensures safe operation.  
- **Soft-Start Function:** Reduces inrush current.
