- **Output Current:** Up to 1A  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin SSOP (Shrink Small Outline Package)  

### **Features:**  
- Integrated N-channel power MOSFET  
- Adjustable output voltage  
- Current-mode PWM control  
- Under-voltage lockout (UVLO)  
- Thermal shutdown protection  
- Short-circuit protection  
- Low quiescent current (typical 2.5mA)  

### **Applications:**  
- Industrial power supplies  
- Automotive systems  
- Telecom power modules  
- Battery-powered equipment
