Description and Introduction

0 The UCC3813N-1 is a high-speed PWM controller manufactured by UNITRODE. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** UNITRODE  
- **Type:** High-Speed PWM Controller  
- **Topology:** Supports forward, flyback, and push-pull configurations  
- **Operating Frequency:** Up to 1MHz  
- **Supply Voltage (VCC):** 12V to 17V (recommended)  
- **Maximum Duty Cycle:** Adjustable, typically up to 100%  
- **Output Drive Current:** 1A peak  
- **Error Amplifier Bandwidth:** 5MHz

- **Undervoltage Lockout (UVLO):** Yes  
- **Package:** 16-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The UCC3813N-1 is a high-performance current-mode PWM controller designed for switching power supplies. It features fast response times, precise duty cycle control, and protection mechanisms such as undervoltage lockout (UVLO) and soft-start. It is commonly used in AC/DC and DC/DC power converters.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Programmable Oscillator:** Allows frequency adjustment via external components.  
- **Synchronous Capability:** Supports external clock synchronization.  
- **Error Amplifier:** High-gain bandwidth for accurate voltage regulation.  
- **Soft-Start:** Prevents inrush current at startup.  
- **UVLO Protection:** Ensures proper operation within voltage limits.  
- **High-Speed Operation:** Suitable for high-frequency power conversion.  

This information is strictly based on UNITRODE's specifications for the UCC3813N-1.
