Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC2805PW 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:** TSSOP-8 (PW)  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Switching Frequency:** Up to 1MHz  
- **Input Voltage Range:** 8.4V to 30V  
- **Output Voltage:** Adjustable via external components  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC2805PW is a high-performance current-mode PWM controller designed for DC-DC power supply applications. It features a fixed-frequency architecture with cycle-by-cycle current limiting, making it suitable for various power topologies, including flyback, forward, boost, and buck converters.  

### **Features:**  
- **Current-Mode Control:** Provides improved loop response and simplified compensation.  
- **Programmable Switching Frequency:** Up to 1MHz operation.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Enhances system reliability.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the input voltage range.  
- **Low Startup Current:** Typically 0.5mA.  
- **High-Current Totem Pole Output:** 1A peak output drive capability.  

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