Description and Introduction

Automotive Catalog Low Power Current Mode Push-Pull PWM The UCC2808A-1Q1 is a high-speed, low-power BiCMOS current-mode PWM controller from Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 8V to 12V  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **UVLO (Undervoltage Lockout):** 7V (turn-on), 6.5V (turn-off)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC2808A-1Q1 is optimized for high-frequency DC-DC power conversion applications. It features current-mode control, cycle-by-cycle current limiting, and a built-in oscillator with synchronization capability.  

### **Features:**  
- **Current-Mode Control** for improved transient response  
- **Programmable Oscillator Frequency** with external resistor  
- **Synchronization Capability** for multi-phase operation  
- **Soft-Start Function** to reduce inrush current  
- **Low Power Consumption** (typically 1.5mA)  
- **Internal Overvoltage Protection**  
- **BiCMOS Technology** for high-speed, low-power operation  

This device is commonly used in switch-mode power supplies (SMPS), DC-DC converters, and power management applications.
