### **Descriptions:**
- The UCC28C43MDREP is a radiation-hardened, high-speed PWM controller designed for aerospace and military applications.  
- It provides precise voltage regulation with current-mode control for improved transient response and simplified feedback loop compensation.  
- The device includes features like under-voltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start capability.  

### **Features:**
- **Radiation-Hardened:** Qualified for space and high-reliability applications.  
- **High-Speed Operation:** Supports switching frequencies up to 1 MHz.  
- **Current-Mode Control:** Enhances loop stability and dynamic response.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Low Propagation Delay:** Enables fast transient response.  
- **Wide Input Voltage Range:** Suitable for various power supply designs.  
- **High Peak Output Current:** Supports driving power MOSFETs efficiently.  

This information is based solely on factual data from the manufacturer's documentation.
