Description and Introduction

1 The UCC3808AD-1 is a high-performance current-mode PWM controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Output Configuration:** Single  
- **Output Type:** Totem Pole  
- **Number of Outputs:** 1  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle (Max):** 100%  
- **Supply Voltage (Vcc):** 8V to 17V  
- **UVLO (Undervoltage Lockout):** 8V (on), 7.25V (off)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC3808AD-1 is a high-speed, low-power current-mode PWM controller optimized for offline and DC-DC power supplies. It features a built-in oscillator, soft-start, and current-sensing capabilities, making it suitable for various power conversion applications.  

### **Features:**  
- **Current-Mode Control:** Provides improved loop response and simplified compensation.  
- **Programmable Oscillator:** Allows flexibility in setting switching frequency.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within supply voltage limits.  
- **Totem-Pole Output:** Capable of driving power MOSFETs directly.  
- **Low Startup Current:** Typically 150µA for efficient operation.  
- **Internal Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  

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