Description and Introduction

Full Bridge Power Amplifier The UC3178QP is a high-performance, fixed-frequency current-mode PWM controller manufactured by UNITRODE. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** Up to 40V  
- **Output Drive Current:** ±2A (peak)  
- **Switching Frequency:** Up to 500kHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin DIP (Dual Inline Package)  

### **Descriptions:**  
- Designed for high-efficiency DC-DC power supply applications.  
- Features current-mode control for improved transient response and loop stability.  
- Includes built-in protections such as undervoltage lockout (UVLO) and cycle-by-cycle current limiting.  

### **Features:**  
- **Current-Mode PWM Control:** Enhances noise immunity and simplifies feedback loop compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Precision Reference Voltage:** 5.1V ±1% for accurate regulation.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **High-Current Totem-Pole Output:** Supports efficient MOSFET driving.  

The UC3178QP is commonly used in switch-mode power supplies (SMPS), inverters, and other power conversion systems requiring robust and precise control.
