Description and Introduction

Economy Primary Side Controller The UCC3809PWTR-1G4 is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI)/Burr-Brown (BB). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Type:** Push-Pull  
- **Topology:** Current-Mode PWM  
- **Frequency - Switching:** Up to 1MHz  
- **Duty Cycle (Max):** 100%  
- **Supply Voltage (Vcc):** 10V to 18V  
- **Operating Temperature:** -40°C to +85°C  
- **Package:** 8-TSSOP (Exposed Pad)  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- Designed for high-frequency power supply applications.  
- Features a high-speed oscillator for efficient switching.  
- Includes built-in protection features such as undervoltage lockout (UVLO) and overcurrent protection.  
- Optimized for low-power standby operation.  

### **Features:**  
- **Current-Mode Control:** Provides improved transient response and simplified loop compensation.  
- **Programmable Oscillator:** Allows flexible frequency setting with an external resistor.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within the supply voltage range.  
- **Low Startup Current:** Enables efficient power-up.  
- **High-Current Totem Pole Output:** Supports fast switching of power MOSFETs.
