- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8 (Exposed Pad)  

### **Descriptions:**  
The LM2696MXA is a high-efficiency, step-up DC-DC converter designed for applications requiring regulated output voltages higher than the input supply. It integrates a power switch and features a fixed-frequency PWM control scheme for stable operation.  

### **Features:**  
- Adjustable output voltage  
- Internal 1.5A power switch  
- Low shutdown current (<1µA)  
- Soft-start functionality  
- Over-temperature protection  
- Under-voltage lockout (UVLO)  
- Thermal shutdown protection  

This device is commonly used in battery-powered systems, portable electronics, and other applications requiring efficient voltage boosting.
