Description and Introduction

High-Performance Current-Mode PWM Controller 14-SOIC 0 to 70 The TL3842BDR is a PWM controller IC manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TL3842BDR  
- **Type:** Current Mode PWM Controller  
- **Package:** SOIC-8 (D)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Input Voltage Range (VCC):** Up to 30V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current (Source/Sink):** 200mA (peak)  
- **Reference Voltage:** 5V (±1%)  
- **Start-up Current:** <1mA  

### **Descriptions:**  
The TL3842BDR is a high-performance current-mode PWM controller designed for DC-DC converter and offline power supply applications. It provides precise control of switching power supplies with features like cycle-by-cycle current limiting, under-voltage lockout (UVLO), and a trimmed oscillator for accurate frequency control.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within specified voltage ranges.  
- **Trimmed Oscillator:** Provides accurate frequency control.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Cycle-by-Cycle Current Limiting:** Enhances system protection.  
- **Low Start-up Current:** Reduces power consumption during start-up.  
- **Adjustable Dead-Time Control:** Optimizes efficiency.  

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