Description and Introduction

BiCMOS PFC/PWM Combination Controller 20-SOIC 0 to 70 The UCC38500DWG4 is a power factor correction (PFC) controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Type:** Power Factor Correction (PFC) Controller  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 15V (typical)  
- **Switching Frequency:** Adjustable (typically up to 200kHz)  
- **Control Method:** Average Current Mode Control  

### **Descriptions:**
- The UCC38500DWG4 is designed for high-power PFC applications, providing efficient power factor correction for AC-DC converters.  
- It uses average current mode control to maintain near-unity power factor and low harmonic distortion.  
- Suitable for boost converter topologies in power supplies.  

### **Features:**
- **Power Factor Correction:** Ensures compliance with regulatory standards.  
- **Average Current Mode Control:** Reduces input current distortion.  
- **Programmable Oscillator:** Adjustable switching frequency.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Low Startup Current:** Minimizes power consumption during startup.  

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