Description and Introduction

Advanced Primary Side Startup Controller The UCC3961D is a high-speed, low-power, dual-channel MOSFET driver manufactured by Texas Instruments.  

### **Specifications:**  
- **Supply Voltage Range:** 4.5V to 18V  
- **Peak Output Current:** ±2A  
- **Propagation Delay (Typical):** 25ns  
- **Rise/Fall Time (Typical):** 15ns (with 1nF load)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
- The UCC3961D is designed to drive both high-side and low-side N-channel MOSFETs in synchronous buck converters.  
- It features independent inputs for each driver, allowing flexible control.  
- The device includes under-voltage lockout (UVLO) protection to prevent improper operation at low supply voltages.
