Description and Introduction

Average Current Mode PWM Controller The UC3848N is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** Up to 30V  
- **Output Frequency:** Adjustable up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP-8 (Plastic Dual In-Line Package)  
- **Current Sensing:** Precision current sensing for peak current-mode control  
- **Start-Up Current:** Low start-up current (<1mA)  
- **Under-Voltage Lockout (UVLO):** Adjustable  

### **Descriptions:**  
The UC3848N is designed for high-efficiency power supply applications, providing precise control in switching power converters. It features a fixed-frequency current-mode architecture, improving loop response and simplifying compensation.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies feedback loop design.  
- **Programmable Oscillator:** Allows frequency adjustment via external components.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Error Amplifier:** High-gain bandwidth for tight output regulation.  
- **Totem-Pole Output:** Capable of driving power MOSFETs directly.  
- **Protection Features:** Includes undervoltage lockout (UVLO) and cycle-by-cycle current limiting.  

This controller is commonly used in offline and DC-DC power supplies, battery chargers, and LED drivers.
