Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3803PW is a PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Current-Mode PWM Controller  
- **Package:** 8-Pin TSSOP (PW)  
- **Operating Voltage Range:** 4.5V to 12V  
- **Switching Frequency:** Up to 1MHz  
- **Output Current:** ±500mA (Peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC3803PW is a high-performance current-mode PWM controller designed for offline and DC-DC power supplies. It provides precise regulation with features like under-voltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start capability.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Programmable Oscillator:** Adjustable switching frequency via external components.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Internal Bandgap Reference:** Provides stable voltage reference for regulation.  
- **Low Startup Current:** Typically 150µA for efficient operation.  

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