Description and Introduction

Two-Phase Interleaved CCM PFC Controller 20-TSSOP -40 to 125 The UCC28070PWG4 is a PFC (Power Factor Correction) controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** PMIC - Power Factor Correction  
- **Package:** TSSOP-20  
- **Operating Temperature Range:** -40°C to +105°C  
- **Input Voltage Range:** 10.5V to 22V  
- **Switching Frequency Range:** Adjustable up to 300kHz  
- **Control Method:** Average Current Mode Control  
- **Topology:** Interleaved Continuous Conduction Mode (CCM) PFC

### **Descriptions:**  
The UCC28070PWG4 is a high-performance, dual-phase, interleaved CCM PFC controller designed for AC/DC power supplies. It improves power factor and reduces input current harmonics while optimizing efficiency. The device supports interleaved operation, which minimizes input and output ripple currents.  

### **Features:**  
- **Interleaved Dual-Phase Operation:** Reduces input/output ripple and component stress.  
- **Average Current Mode Control:** Ensures accurate current shaping for high power factor.  
- **Programmable Switching Frequency:** Up to 300kHz for design flexibility.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Brownout Protection:** Detects low input voltage conditions.  
- **Open-Loop Protection:** Ensures safe operation under fault conditions.  
- **Low Startup and Operating Current:** Enhances efficiency.
