Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC2801 is a high-speed PWM controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 8V to 35V  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Propagation Delay:** 50ns  
- **Soft-Start Capability:** Yes  
- **Undervoltage Lockout (UVLO):** Adjustable  

### **Descriptions:**  
The UCC2801 is a high-performance current-mode PWM controller designed for power supply applications. It provides precise control for switching power converters, supporting both voltage and current-mode feedback. The device features high-speed operation, making it suitable for high-frequency DC-DC converters, offline power supplies, and motor control applications.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Adjustable UVLO:** Allows customization of startup voltage thresholds.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Wide Input Voltage Range:** Operates from 8V to 35V.  
- **High Output Drive Capability:** ±1A peak output current for fast MOSFET switching.  
- **Error Amplifier with High Bandwidth:** Ensures stable feedback loop performance.  
- **Low Propagation Delay:** Improves transient response.  

This information is based on the manufacturer's datasheet and technical documentation.
