Description and Introduction

1 The UCC2809D-2 is a high-speed PWM controller manufactured by UNITRODE. Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** UNITRODE  
- **Type:** High-speed PWM controller  
- **Package:** SOIC-8  
- **Operating Voltage Range:** Typically 8V to 17V  
- **Switching Frequency:** Adjustable, typically up to 1MHz  
- **Output Drive Current:** Capable of driving power MOSFETs directly  
- **Duty Cycle Range:** Up to 100%  
- **Error Amplifier Bandwidth:** High-speed response for tight regulation  
- **Protection Features:** Includes undervoltage lockout (UVLO) and soft-start  

### **Descriptions:**  
- The UCC2809D-2 is a pulse-width modulation (PWM) controller designed for high-frequency power supply applications.  
- It is optimized for use in DC-DC converters, offline power supplies, and other switch-mode power systems.  
- The device integrates precision reference, error amplifier, oscillator, and PWM comparator for efficient power regulation.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Precision Voltage Reference:** Ensures accurate regulation.  
- **Adjustable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Wide Operating Voltage Range:** Suitable for various power supply designs.  
- **Direct MOSFET Drive:** Eliminates the need for additional drive circuitry.  
- **Thermally Enhanced Package:** SOIC-8 for improved heat dissipation.  

This information is strictly based on the manufacturer's specifications and does not include any additional recommendations.
