Description and Introduction

Low Power, Dual Output, Current Mode PWM Controller The UCC2806N is a high-speed BiCMOS current-mode PWM controller manufactured by Texas Instruments.  

### **Key Specifications:**  
- **Input Voltage Range:** 10V to 20V  
- **Operating Frequency:** Up to 1MHz  
- **Output Current:** ±2A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Soft-Start Capability:** Adjustable  
- **Error Amplifier Bandwidth:** 5MHz  
- **Propagation Delay:** 50ns  

### **Descriptions:**  
The UCC2806N is designed for high-frequency switching power supplies, providing precise current-mode control with fast response. It includes features like under-voltage lockout (UVLO), cycle-by-cycle current limiting, and a totem-pole output stage for driving power MOSFETs efficiently.  

### **Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Low Startup Current:** Typically 150µA.  
- **High-Speed Shutdown:** Fast response to fault conditions.  
- **BiCMOS Technology:** Combines high speed with low power consumption.  

This IC is commonly used in DC-DC converters, offline power supplies, and telecom power systems.

- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC2806N is a high-performance PWM controller designed for power supply applications. It features current-mode control for improved transient response and cycle-by-cycle current limiting. The device includes an onboard oscillator, error amplifier, and high-current totem-pole output for driving power MOSFETs.  

### **Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **High-Speed Switching:** Supports frequencies up to 1MHz.  
- **Low Startup Current:** Typically 150µA for efficient operation.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Totem-Pole Output:** Provides high peak current for fast MOSFET switching.  

This information is based on TI's official documentation for the UCC2806N.
