Description and Introduction

Low Power, Dual Output, Current Mode PWM Controller The UCC2806D is a BiCMOS advanced phase-shifted PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Control Method:** Phase-Shifted PWM  
- **Topology:** Full-Bridge, Half-Bridge  
- **Operating Frequency:** Up to 1MHz  
- **Supply Voltage (VCC):** 10V to 18V  
- **Output Current (Source/Sink):** 1A (Peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Propagation Delay:** 50ns (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The UCC2806D is designed for high-frequency, high-efficiency power conversion applications. It provides precise phase-shifted PWM control, enabling zero-voltage switching (ZVS) in resonant and quasi-resonant converters. The device integrates features such as programmable dead-time control, soft-start, and error amplification for improved power supply performance.  

### **Features:**  
- **Phase-Shifted Control:** Enables ZVS for reduced switching losses.  
- **Programmable Dead Time:** Adjustable delay between switching transitions.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Error Amplifier:** Provides closed-loop feedback control.  
- **Synchronization Capability:** Allows multiple controllers to sync for multi-phase operation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within supply range.  
- **BiCMOS Technology:** Low power consumption and high-speed switching.
