Description and Introduction

1 The UCC3809PW-1 is a PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Frequency Range:** Up to 1MHz  
- **Operating Voltage Range:** 8V to 17V  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current (Source/Sink):** 1A (Peak)  
- **Package:** 8-Pin TSSOP (PW)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC3809PW-1 is a high-performance current-mode PWM controller designed for offline and DC-DC power supplies. It features a fast response time, high-frequency operation, and precise duty cycle control.  

### **Features:**  
- **Current-Mode Control:** Ensures cycle-by-cycle current limiting.  
- **Programmable Oscillator:** Adjustable frequency up to 1MHz.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Low Startup Current:** Reduces power consumption during standby.  
- **Leading Edge Blanking:** Improves noise immunity in current sensing.  

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