- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Propagation Delay:** 50ns (Typical)  

### **Descriptions:**
- The UC28025NG4 is a high-performance pulse-width modulation (PWM) controller designed for power supply applications.  
- It features fast response times and high-frequency operation, making it suitable for switch-mode power supplies (SMPS), DC-DC converters, and motor control systems.  
- The device includes an onboard error amplifier, oscillator, PWM comparator, and high-current totem-pole output drivers.  

### **Features:**
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Precision Reference:** Internal 5.1V bandgap reference with ±1% accuracy.  
- **High-Current Output:** 1A peak output drive capability.  
- **Adjustable Dead-Time Control:** Allows optimization of power efficiency.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Synchronization Capability:** Can be synchronized to an external clock.  
- **Wide Supply Voltage Range:** Operates from a wide input voltage range (up to 40V).  

This information is based on Texas Instruments' official documentation for the UC28025NG4. For detailed electrical characteristics and application notes, refer to the datasheet.
