- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead MSOP  

### **Descriptions:**  
- The LT1947 is a constant-frequency, current-mode step-down DC/DC converter.  
- It features a low-dropout design, allowing it to maintain regulation with small input-output differentials.  
- Includes internal soft-start, thermal shutdown, and current limit protection.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 3.6V to 36V.  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output voltage.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **1.2MHz Switching Frequency:** Allows for small external components.  
- **Protection Features:** Overcurrent, thermal shutdown, and soft-start.
