Description and Introduction

High Speed PWM Controller The UC282-3 is a high-speed PWM controller manufactured by ON Semiconductor. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Manufacturer:** ON Semiconductor  
- **Type:** High-Speed PWM Controller  
- **Topology:** Voltage Mode or Current Mode Control  
- **Operating Frequency:** Up to 1 MHz  
- **Supply Voltage (VCC):** Typically 8V to 35V  
- **Output Drive Current:** Up to 2A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** High-speed for fast response  
- **Protection Features:** Under-voltage lockout (UVLO), soft-start, overcurrent protection  

### **Descriptions:**  
The UC282-3 is a pulse-width modulation (PWM) controller designed for high-frequency power supply applications. It supports both voltage-mode and current-mode control, making it versatile for various DC-DC converter designs. The device is optimized for high-speed switching, enabling efficient power conversion in demanding applications.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1 MHz.  
- **Flexible Control Modes:** Compatible with voltage-mode and current-mode topologies.  
- **High Output Drive Capability:** 2A peak output current for driving power MOSFETs.  
- **Wide Input Voltage Range:** Operates from 8V to 35V.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Precision Reference:** Internal 5.1V reference with tight tolerance.  
- **Protection Circuits:** Includes under-voltage lockout (UVLO) and overcurrent protection.  
- **Thermally Enhanced Package:** Available in a robust package for improved thermal performance.
