Description and Introduction

High Performance Current Mode Controllers The UC2842BNG is a high-performance current-mode PWM controller manufactured by Texas Instruments. Here are the factual details about its Pb-free specifications, descriptions, and features:

### **Pb-Free Specifications**  
- The UC2842BNG is **Pb-free (RoHS compliant)**.  
- It meets the requirements of the **Restriction of Hazardous Substances (RoHS) Directive**.  

### **Descriptions**  
- The UC2842BNG is a **fixed-frequency current-mode PWM controller**.  
- It is designed for **offline and DC-DC converter applications**.  
- Features include **trimmed oscillator discharge current**, **automatic feed-forward compensation**, and **current-sensing comparator with leading-edge blanking**.  
- The device is available in an **8-pin PDIP (N) package**.  

### **Features**  
- **Current-Mode Operation**: Provides improved line regulation and simplified loop compensation.  
- **Automatic Feed-Forward Compensation**: Ensures consistent performance across input voltage variations.  
- **Trimmed Oscillator Discharge Current**: Ensures precise duty cycle control.  
- **Undervoltage Lockout (UVLO)**: Ensures reliable startup and shutdown.  
- **High-Current Totem Pole Output**: Capable of driving power MOSFETs directly.  
- **Pulse-by-Pulse Current Limiting**: Enhances system protection.  
- **Internal Soft-Start**: Reduces inrush current during startup.  
- **Operating Frequency Up to 500 kHz**: Suitable for high-frequency switching applications.  

These details are based on the manufacturer's specifications for the UC2842BNG.
