- **Shutdown Current:** <1µA  
- **Internal Switch Current Limit:** 1.5A  

### **Descriptions:**  
The LT1931AES5#PBF is a high-efficiency, low-noise, step-up DC/DC converter designed for applications requiring a regulated output voltage higher than the input supply. It features a built-in NPN switch and operates at a fixed 1.2MHz switching frequency, allowing the use of small external components.  

### **Features:**  
- **Wide Input Voltage Range:** 1.2V to 16V  
- **Adjustable Output Voltage (up to 40V)**  
- **High Switching Frequency (1.2MHz)**  
- **Low Shutdown Current (<1µA)**  
- **Internal Soft-Start**  
- **Short-Circuit Protection**  
- **Thermal Shutdown Protection**  
- **Small SOT-23-5 Package**  

This device is commonly used in battery-powered systems, portable instruments, and other applications requiring efficient power conversion.
