Description and Introduction

32V; 1000mW; programmable off-line PWM controller The UC2840N is a pulse width modulation (PWM) controller IC manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Type:** Current Mode PWM Controller  
- **Operating Voltage Range:** 8V to 30V  
- **Output Current:** Up to 1A (peak)  
- **Switching Frequency:** Adjustable (up to 500kHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** PDIP-8 (Plastic Dual In-Line Package)  

### **Descriptions:**  
The UC2840N is a high-performance current-mode PWM controller designed for offline and DC-DC converter applications. It provides precise regulation with features like cycle-by-cycle current limiting, adjustable switching frequency, and soft-start capability.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Totem Pole Output:** Supports high-current MOSFET or bipolar transistor drivers.  
- **Low Startup Current:** Reduces power consumption during initial operation.  

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