Description and Introduction

Resonant-Mode Power Supply Controllers The UC3861N is a power management IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Function:** Resonant Mode Controller  
- **Topology:** Supports resonant mode power conversion  
- **Operating Voltage Range:** Typically 10V to 20V  
- **Output Drive Capability:** High-current totem-pole outputs for driving power MOSFETs  
- **Frequency Range:** Adjustable oscillator for resonant operation  
- **Protection Features:** Overcurrent protection, undervoltage lockout (UVLO)  
- **Package:** PDIP-16 (Plastic Dual In-Line Package)  

### **Descriptions and Features:**  
- Designed for efficient resonant mode power supply control.  
- Optimized for zero-voltage switching (ZVS) and zero-current switching (ZCS) topologies.  
- Includes an adjustable oscillator for precise frequency control.  
- Features a high-current output stage for direct MOSFET driving.  
- Provides soft-start functionality for controlled startup.  
- Includes protection mechanisms such as undervoltage lockout (UVLO) to ensure safe operation.
