### **Descriptions:**
The **UC2842AD8TRG4** is a high-performance, fixed-frequency PWM controller designed for DC-DC converter applications. It operates in **current-mode control**, providing improved loop response and simplified compensation. The device includes features like **undervoltage lockout (UVLO)**, **current limiting**, and **programmable oscillator frequency**. It is commonly used in **offline and DC-DC power supplies**.

### **Features:**
- **Current-Mode PWM Control** for improved transient response  
- **Automatic Feed-Forward Compensation**  
- **Latching PWM for Cycle-by-Cycle Current Limiting**  
- **Internal Trimmed Bandgap Reference (5V ±1%)**  
- **High-Current Totem Pole Output (1A Peak)**  
- **Low Startup Current (<1mA)**  
- **Programmable Oscillator with Sync Capability**  
- **Undervoltage Lockout (UVLO) with Hysteresis** (8.4V On / 7.6V Off)  
- **SOIC-8 Package for Space-Constrained Designs**  

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