Description and Introduction

Resonant Fluorescent Lamp Driver The UC2871DW is a high-performance 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)  
- **Part Number:** UC2871DW  
- **Type:** PWM Controller  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** Typically operates with a supply voltage of up to 40V  
- **Switching Frequency:** Adjustable, typically up to 1MHz  
- **Output Drive Capability:** Capable of driving external MOSFETs or IGBTs  
- **Protection Features:** Includes overcurrent protection, undervoltage lockout (UVLO), and soft-start capability  

### **Descriptions:**  
The UC2871DW is a pulse-width modulation (PWM) controller designed for high-efficiency power supply applications. It provides precise control for switching power converters, making it suitable for DC-DC converters, offline power supplies, and motor control systems. The device integrates multiple protection features to enhance system reliability.

### **Features:**  
- **Programmable PWM Operation:** Allows flexible frequency and duty cycle control.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Overcurrent Protection:** Safeguards the circuit from excessive current.  
- **High-Current Totem-Pole Outputs:** Capable of driving power MOSFETs or IGBTs directly.  
- **Wide Operating Voltage Range:** Supports various power supply configurations.  
- **Adjustable Dead-Time Control:** Optimizes efficiency in synchronous rectification applications.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official TI datasheet for the UC2871DW.
