Description and Introduction

Current-Mode PWM Controller The TL2842P is a pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range (VCC):** 8V to 30V  
- **Operating Frequency:** Up to 500 kHz  
- **Output Duty Cycle:** Adjustable up to 100%  
- **Output Current (Source/Sink):** 200 mA (peak)  
- **Error Amplifier Gain Bandwidth:** 1 MHz  
- **Reference Voltage (VREF):** 5V ±1%  
- **Quiescent Current:** 6 mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The TL2842P is a fixed-frequency current-mode PWM controller designed for DC-DC converter applications. It provides high-performance control for power supplies with features like cycle-by-cycle current limiting and undervoltage lockout (UVLO).  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Programmable Oscillator:** Allows flexible frequency adjustment.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Error Amplifier:** Provides precise voltage regulation.  
- **Totem-Pole Output:** Supports direct drive of power MOSFETs.  
- **Cycle-by-Cycle Current Limiting:** Enhances system protection.  

This information is sourced from the official Texas Instruments datasheet for the TL2842P.
