Description and Introduction

Current-Mode PWM Controller 8-SOIC 0 to 70 The TL3843DRG4-8 is a current-mode PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TL3843DRG4-8  

### **Description:**  
The TL3843DRG4-8 is a high-performance current-mode PWM controller designed for DC-DC converter applications. It provides precise control for power supply designs with features like adjustable switching frequency, cycle-by-cycle current limiting, and under-voltage lockout (UVLO).  

### **Key Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Adjustable Frequency Operation:** Allows optimization for efficiency and component size.  
- **Under-Voltage Lockout (UVLO):** Ensures proper startup and shutdown behavior.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs (up to 1A peak).  
- **Cycle-by-Cycle Current Limiting:** Protects against overload conditions.  
- **Low Startup and Operating Current:** Reduces power consumption.  
- **Error Amplifier with Reference:** Provides stable feedback control.  
- **Duty Cycle Range:** Up to 100% (with external adjustments).  

### **Applications:**  
- Switch-mode power supplies (SMPS)  
- DC-DC converters  
- Battery chargers  
- Power management systems  

### **Package:** SOIC-8 (DRG4)
