Description and Introduction

Current-Mode PWM Controller The TL3843DR-8 is a current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range (VCC):** 8.5V to 30V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Up to 500 kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  
- **Output Drive Current:** ±200mA (peak)  
- **Reference Voltage (VREF):** 5V ±1%  
- **Start-Up Current:** <1mA  
- **UVLO (Undervoltage Lockout):** 8V (on), 7.6V (off)  

### **Descriptions:**  
The TL3843DR-8 is a high-performance PWM controller designed for DC-DC converter applications. It features current-mode control for improved loop response and includes protections such as undervoltage lockout (UVLO) and cycle-by-cycle current limiting.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Adjustable Frequency:** Set via external timing components.  
- **Precision Reference:** 5V ±1% for stable regulation.  
- **Low Start-Up Current:** Enables efficient power-up.  
- **High Output Drive:** Supports direct MOSFET drive.  
- **Wide Input Voltage Range:** Suitable for various power supply designs.  
- **SOIC-8 Package:** Compact and suitable for space-constrained applications.  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to TI's official documentation.
