Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3804 is a high-performance current-mode PWM controller manufactured by Texas Instruments. Below are the key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 10V to 22V  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Start-Up Current:** 150µA (typical)  
- **Error Amplifier Bandwidth:** 5MHz  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The UCC3804 is a low-power, fixed-frequency current-mode PWM controller designed for offline and DC-DC power supplies.  
- It includes an integrated high-current totem-pole output driver for direct MOSFET control.  
- Features an adjustable oscillator, precision reference, and soft-start functionality.  

### **Features:**  
- **Current-Mode Control:** Provides cycle-by-cycle current limiting.  
- **Low Power Consumption:** Optimized for energy-efficient applications.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Internal Leading-Edge Blanking:** Improves noise immunity in current sensing.  

The UCC3804 is commonly used in switch-mode power supplies (SMPS), AC-DC converters, and isolated power applications.
