Description and Introduction

Dual Interleaved PWM Controller with Programmable Max Duty Cycle The UCC28220 is a high-performance PWM controller manufactured by UNITRODE. Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 15V  
- **Operating Frequency Range:** Up to 2 MHz  
- **Output Drive Current:** 2A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Propagation Delay:** 30ns (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** SOIC-16, TSSOP-16  

### **Descriptions:**  
The UCC28220 is a high-speed, dual-output synchronous buck controller designed for high-efficiency DC-DC power conversion. It provides precise PWM control for synchronous rectification applications, optimizing power delivery in high-frequency switching power supplies.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 2 MHz.  
- **Dual Output Drivers:** Independent high-side and low-side gate drivers.  
- **Adaptive Dead-Time Control:** Minimizes body diode conduction losses.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Overcurrent Protection:** Enhances system reliability.  
- **Synchronization Capability:** Allows external clock synchronization.
