Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC2804D is a high-performance, current-mode PWM controller manufactured by Texas Instruments.  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range:** Up to 30V  
- **Operating Frequency:** Adjustable up to 1MHz  
- **Output Drive Current:** ±1A peak  
- **Duty Cycle Range:** 0% to 100%  
- **Start-Up Current:** 0.5mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC2804D is designed for offline and DC-DC power supply applications. It provides precise control for switching power supplies with features like adjustable frequency, soft-start, and cycle-by-cycle current limiting.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Adjustable Frequency:** Allows flexibility in design.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Low Start-Up Current:** Enhances efficiency.  
- **High Output Drive:** Supports fast switching of power MOSFETs.  

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