Description and Introduction

1 The UCC3807D-3 is a high-performance current-mode PWM controller manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** Up to 30V  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Start-Up Current:** 150µA (typical)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-8  

### **Descriptions:**
- The UCC3807D-3 is designed for offline and DC-DC power supply applications.  
- It features a high-speed current-mode control architecture for improved transient response.  
- Includes built-in protections such as undervoltage lockout (UVLO), overcurrent protection, and soft-start.  

### **Features:**
- **Current-Mode Control:** Enhances loop stability and simplifies compensation.  
- **Programmable Oscillator:** Allows frequency adjustment via external components.  
- **Low Start-Up Current:** Reduces power consumption during initial operation.  
- **Integrated Soft-Start:** Prevents excessive inrush current.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **High-Current Totem Pole Output:** Supports direct MOSFET driving.  

The UCC3807D-3 is commonly used in switch-mode power supplies (SMPS), AC-DC converters, and other power management applications.
