Description and Introduction

Resonant-Mode Power Supply Controllers The UC3863N is a power management IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Function:** Resonant Mode Controller  
- **Topology:** Resonant, Half-Bridge, or Full-Bridge  
- **Operating Frequency:** Up to 1MHz  
- **Supply Voltage (VCC):** 12V to 20V  
- **Output Current (Source/Sink):** 500mA (Peak)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** PDIP-16  

### **Descriptions:**  
The UC3863N is designed for high-efficiency resonant-mode power conversion applications. It provides precise control for resonant power supplies, enabling soft-switching techniques to reduce switching losses and EMI.  

### **Features:**  
- **Programmable Dead-Time Control** – Adjusts dead time for optimal switching.  
- **Voltage-Controlled Oscillator (VCO)** – Allows frequency modulation.  
- **Soft-Start Function** – Prevents inrush current during startup.  
- **Error Amplifier** – Ensures stable feedback control.  
- **Under-Voltage Lockout (UVLO)** – Protects against low supply voltage.  
- **High-Current Totem-Pole Outputs** – Drives power MOSFETs efficiently.  

This IC is commonly used in high-frequency power supplies, induction heating, and DC-DC converters.
