Description and Introduction

BiCMOS POWER FACTOR PREREGULATOR The UCC3817APWRG4 is a BiCMOS advanced PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range (VCC):** 10V to 17V (operating)  
- **Maximum Duty Cycle:** 100%  
- **Switching Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-16  

### **Descriptions:**  
The UCC3817APWRG4 is designed for high-performance power supply applications. It features precise duty cycle control, cycle-by-cycle current limiting, and soft-start functionality. It is optimized for offline and DC-DC converters.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within specified voltage range.  
- **Synchronizable Oscillator:** Allows synchronization to an external clock.  
- **Error Amplifier:** Provides high-gain bandwidth for accurate regulation.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  

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