Description and Introduction

High-Performance Current-Mode PWM Controller 8-PDIP 0 to 70 The TL3844BP is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range (VCC):** 8.5V to 30V  
- **Operating Frequency Range:** Up to 500kHz  
- **Output Duty Cycle:** 0% to <100%  
- **Output Current (Peak):** ±1A (sink/source)  
- **Reference Voltage (VREF):** 5V ±1%  
- **Error Amplifier Gain Bandwidth:** 1MHz (typical)  
- **Start-Up Current:** 1mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The TL3844BP is a fixed-frequency pulse-width modulation (PWM) controller optimized for DC-DC converter and power supply applications.  
- It operates in current-mode control, providing improved loop response and simplified feedback compensation.  
- Includes an undervoltage lockout (UVLO) feature to ensure proper start-up and shutdown.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Adjustable Oscillator Frequency:** Set by external timing components.  
- **Undervoltage Lockout (UVLO):** Ensures reliable operation under low-voltage conditions.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Internal Trimmed Bandgap Reference:** Provides stable 5V reference for feedback.  
- **Pulse-by-Pulse Current Limiting:** Protects against overloads.  
- **Soft-Start Capability:** Reduces inrush current during start-up.
