Description and Introduction

BiCMOS PFC/PWM Combination Controller The UCC38501DWTR is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Voltage Range:** Up to 400V DC  
- **Operating Frequency:** Adjustable up to 200 kHz  
- **Control Method:** Average current mode control  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 10V to 18V  
- **Peak Gate Drive Current:** ±1.5A  

### **Descriptions:**  
The UCC38501DWTR is a high-performance PFC controller designed for boost-type power factor correction circuits. It ensures near-unity power factor and low harmonic distortion in AC/DC power supplies.  

### **Features:**  
- **Power Factor Correction (PFC):** Achieves >0.99 power factor  
- **Low THD (Total Harmonic Distortion):** Minimizes input current distortion  
- **Programmable Switching Frequency:** Allows optimization of efficiency and component size  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage  
- **Soft-Start Function:** Reduces inrush current  
- **Zero-Current Detection (ZCD):** Enhances efficiency in discontinuous conduction mode (DCM)  
- **Current Sense Input:** Supports average current mode control
