Description and Introduction

1 The UCC3580Q-3 is a PWM controller IC manufactured by UNITRODE. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** UNITRODE  
- **Output Type:** PWM (Pulse Width Modulation)  
- **Topology:** Supports flyback, forward, and buck-boost converters  
- **Operating Frequency:** Adjustable up to 500 kHz  
- **Supply Voltage (VCC):** 8V to 20V  
- **Output Drive Current:** 1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Protection Features:** Overcurrent protection, undervoltage lockout (UVLO)  
- **Package:** SOIC-16  

### **Descriptions:**  
The UCC3580Q-3 is a high-performance PWM controller designed for switch-mode power supplies (SMPS). It provides precise control for power conversion applications, including isolated and non-isolated topologies.  

### **Features:**  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Synchronization Capability:** Can sync to an external clock.  
- **Error Amplifier:** Includes a high-gain error amplifier for feedback loop stability.  
- **Current Sensing:** Supports cycle-by-cycle current limiting.  
- **Low Power Consumption:** Suitable for energy-efficient designs.  

This information is based solely on the UNITRODE datasheet for the UCC3580Q-3.
