Description and Introduction

4.5V to 18V Input, Low Pin Count Synchronous Buck Controller with Power Good 10-VSON -40 to 85 The TPS40193DRCRG4 is a synchronous buck controller manufactured by Texas Instruments (TI) and formerly by Burr-Brown (BB).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.6V to 5.5V  
- **Switching Frequency:** Adjustable from 200kHz to 1MHz  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-VSON (3mm x 3mm)  
- **Control Method:** Voltage Mode  
- **Features:**  
  - Synchronous rectification  
  - Adjustable soft-start  
  - Power-good output  
  - Overcurrent protection (OCP)  
  - Thermal shutdown  

### **Descriptions and Features:**  
The TPS40193DRCRG4 is a high-efficiency, wide-input-voltage synchronous buck controller designed for point-of-load (POL) applications. It supports a wide input voltage range and provides precise output voltage regulation.  

Key features include:  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Synchronous Operation:** Improves efficiency by reducing conduction losses.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Power-Good Indicator:** Monitors output voltage status.  
- **Protection Features:** Includes overcurrent and thermal shutdown for reliability.  

This device is commonly used in telecom, industrial, and computing applications.
