Description and Introduction

Current-Mode PWM Controller 8-SOIC 0 to 70 The UC3843D8TRG4 is a current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage (VIN):** Up to 30V  
- **Output Voltage (VOUT):** Adjustable  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UC3843D8TRG4 is designed for DC-DC converter applications, providing precise control for switching power supplies. It features a fixed-frequency oscillator, error amplifier, and current-sensing comparator for reliable performance in power management systems.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper start-up and shutdown.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Programmable Oscillator:** Allows flexible frequency setting.  
- **Pulse-by-Pulse Current Limiting:** Enhances system protection.  
- **Low Start-Up Current:** Typically 0.5mA.  

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