Description and Introduction

Natural Interleaved Dual-Phase Transition-Mode PFC Controller The UCC28060 is a dual-phase, transition-mode power factor correction (PFC) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 85 VAC to 265 VAC  
- **Output Power Range:** Up to 300 W (single-phase) or 600 W (interleaved dual-phase)  
- **Switching Frequency:** Transition-mode (boundary conduction mode) operation  
- **Operating Frequency Range:** Adjustable, typically up to 300 kHz  
- **Supply Voltage (VCC):** 10.5 V to 21 V  
- **Maximum Duty Cycle:** 97%  
- **Current Sense Input Range:** ±500 mV  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** 16-pin SOIC (D)  

### **Descriptions:**  
- The UCC28060 is designed for high-efficiency, interleaved PFC applications.  
- It enables dual-phase operation, reducing input current ripple and output capacitor requirements.  
- Features transition-mode control for near-unity power factor and low THD (Total Harmonic Distortion).  
- Includes integrated MOSFET drivers and synchronization for interleaved operation.  

### **Features:**  
- **Dual-Phase Interleaved Operation:** Reduces input/output ripple current.  
- **Transition-Mode Control:** Ensures high power factor (>0.99) and low THD.  
- **Average Current Mode Control:** Improves noise immunity.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and EMI.  
- **Integrated High-Current Gate Drivers:** Supports MOSFETs directly.  
- **Soft-Start & Fault Protection:** Includes overvoltage (OVP), undervoltage (UVP), and open-loop protection.  
- **Master-Slave Synchronization:** Enables multi-phase operation.
