Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3804PW is a PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Current-Mode PWM Controller  
- **Package:** 8-Pin TSSOP (PW)  
- **Operating Voltage Range:** 4.5V to 12V  
- **Maximum Switching Frequency:** 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC3804PW is a high-performance, current-mode PWM controller designed for offline and DC-DC power supplies. It features a fast start-up time, low power consumption, and precise duty cycle control. The device is optimized for flyback, forward, and boost converter topologies.  

### **Features:**  
- **Current-Mode Control:** Provides improved loop response and simplified compensation.  
- **Programmable Oscillator:** Allows adjustable switching frequency up to 1MHz.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the supply voltage range.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **High-Current Totem Pole Output:** Supports direct drive of power MOSFETs.  
- **Low Startup Current:** Typically 100µA for efficient operation.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  

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