- **Package Type:** 16-pin CERDIP (J-lead)  

### **Descriptions:**  
- The UC1525AJ/883B is a radiation-hardened, military-grade PWM controller designed for high-reliability applications.  
- It is optimized for switch-mode power supply (SMPS) and DC-DC converter designs.  
- Features include adjustable dead-time control, soft-start capability, and under-voltage lockout (UVLO).  
- Suitable for aerospace, defense, and other harsh-environment applications.  

### **Features:**  
- **Precision Reference:** 5.1V ±1% trimmed bandgap reference.  
- **Synchronizable Oscillator:** Allows for master-slave operation.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Soft-Start Control:** Reduces inrush current during startup.  
- **Dual Error Amplifiers:** Provides flexibility in feedback loop design.  
- **Shutdown Function:** Allows for immediate shutdown via an external signal.  
- **Radiation-Hardened:** Meets MIL-STD-883B standards for radiation tolerance.  
- **High Noise Immunity:** Designed for stable operation in noisy environments.  

This information is strictly based on the manufacturer's datasheet and specifications.
