Description and Introduction

Low Power, Dual Output, Current Mode PWM Controller The UCC3806N is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range (VCC):** 10V to 20V  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Start-Up Current:** 150µA (typical)  
- **Quiescent Current:** 3mA (typical)  
- **Error Amplifier Bandwidth:** 5MHz  
- **Propagation Delay:** 50ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The UCC3806N is a current-mode PWM controller optimized for high-frequency power supply applications. It provides precise control for DC-DC converters, featuring fast response and high efficiency. The device includes an integrated error amplifier, oscillator, current sensing comparator, and totem-pole output driver.  

### **Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Programmable Oscillator:** Allows flexible frequency adjustment.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.  
- **High-Speed Output Driver:** Supports fast switching for MOSFETs.  
- **Low Start-Up Current:** Enables efficient operation in standby modes.  
- **Wide Duty Cycle Range:** Suitable for various converter topologies.  

This information is based on TI's official datasheet for the UCC3806N.
