Description and Introduction

Current mode PWM controller The part KA3882D is manufactured by Fairchild Semiconductor (FSC). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Fairchild Semiconductor (FSC)  
- **Type:** Switching Regulator IC  
- **Package:** SOP-8 (Small Outline Package)  
- **Input Voltage Range:** 8V to 35V  
- **Output Voltage:** Adjustable  
- **Switching Frequency:** 52 kHz (typical)  
- **Output Current:** Up to 1.5A  
- **Operating Temperature Range:** -25°C to +85°C  

### **Descriptions:**  
- The KA3882D is a pulse-width modulation (PWM) controller IC designed for DC-DC converter applications.  
- It is a fixed-frequency current-mode controller, optimized for offline and DC-DC power supplies.  
- The device includes an oscillator, PWM comparator, latch, and high-current totem-pole output.  

### **Features:**  
- **Current-Mode Operation:** Provides improved transient response and simplified loop compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the input voltage range.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs.  
- **Low Standby Current:** Enhances efficiency in standby mode.  
- **Cycle-by-Cycle Current Limiting:** Protects against overload conditions.  

This information is strictly factual and sourced from the available knowledge base.
