- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 10-VSON (3mm x 3mm)  

### **Descriptions:**  
The TPS40193DRCR is a high-performance, wide-input-voltage synchronous buck controller designed for power supply applications. It supports high-efficiency step-down conversion with adjustable frequency and integrated gate drivers.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 25V input.  
- **Adjustable Output Voltage:** Configurable from 0.6V to 6V.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Switching Frequency:** 200kHz to 1MHz for optimization of size and efficiency.  
- **Integrated Gate Drivers:** Reduces external component count.  
- **Programmable Soft-Start:** Prevents inrush current.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Overcurrent & Overtemperature Protection:** Enhances system reliability.  
- **Thermally Enhanced Package:** 10-VSON for improved heat dissipation.  

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

(Note: "BB" may refer to a bulk packaging option, but this is not explicitly confirmed in the datasheet.)
