Description and Introduction

Current-Mode PWM Controller The UC2842D8 is a high-performance current-mode PWM controller manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments  

### **Part Number:**  
UC2842D8  

### **Description:**  
The UC2842D8 is a fixed-frequency pulse-width modulation (PWM) controller designed for DC-DC converter and power supply applications. It operates in current-mode control, providing precise regulation and improved transient response.  

### **Key Features:**  
- **Current-Mode Control:** Enhances loop stability and simplifies feedback compensation.  
- **Adjustable Switching Frequency:** Up to 500 kHz.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation with hysteresis for reliable startup.  
- **Low Startup Current:** Typically 0.5 mA, reducing power consumption during startup.  
- **High-Current Totem Pole Output:** Capable of driving power MOSFETs directly (up to ±1A peak).  
- **Pulse-by-Pulse Current Limiting:** Protects against overcurrent conditions.  
- **Internal Trimmed Bandgap Reference:** Provides a stable 5V reference (±1% accuracy).  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Duty Cycle Clamp:** Prevents transformer saturation in forward converters.  

### **Package:**  
- **D8 (SOIC-8):** Surface-mount package with 8 pins.  

### **Applications:**  
- Switch-mode power supplies (SMPS)  
- DC-DC converters  
- Offline power supplies  
- Battery chargers  
- LED drivers  

### **Operating Conditions:**  
- **Input Voltage (VCC):** Up to 30V  
- **Operating Temperature Range:** -40°C to +85°C  

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