Description and Introduction

SMPS Controller The KA3882C is a switching regulator controller IC manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** FAIR (Fairchild Semiconductor)  
- **Type:** Switching Regulator Controller  
- **Package:** Typically available in DIP-8 or SOIC-8  
- **Input Voltage Range:** 7V to 30V  
- **Operating Frequency:** Adjustable up to 500kHz  
- **Output Current:** Up to 1.5A (dependent on external components)  
- **Duty Cycle:** Adjustable (typically up to 90%)  
- **Reference Voltage:** 5V (internal)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The KA3882C is a fixed-frequency current-mode PWM controller designed for DC-DC converter applications. It provides high efficiency and precise regulation in power supply designs, including flyback, forward, and boost converters.  

### **Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Under-Voltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Pulse-by-Pulse Current Limiting:** Protects against overloads.  
- **Error Amplifier:** Provides feedback loop stability.  
- **Totem-Pole Output:** Supports direct drive of power MOSFETs.  

This information is based on the manufacturer's datasheet and technical documentation.

Description and Introduction

SMPS Controller The KA3882C is a PWM (Pulse Width Modulation) controller IC manufactured by **FAIRCHILD**. Below are its specifications, descriptions, and features based on available information:  

### **Specifications:**  
- **Manufacturer:** FAIRCHILD  
- **Type:** Current Mode PWM Controller  
- **Operating Voltage Range:** Typically 8V to 30V  
- **Output Drive Current:** Up to 1A (peak)  
- **Switching Frequency:** Adjustable (commonly up to 500kHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** Typically 1MHz  
- **Package Type:** DIP-8 or SOIC-8  

### **Descriptions:**  
The KA3882C is a high-performance current-mode PWM controller designed for switch-mode power supply (SMPS) applications. It provides precise regulation and protection features, making it suitable for offline and DC-DC converters.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Enhances system protection.  
- **Internal Trimmed Bandgap Reference:** Provides stable voltage regulation.  
- **Totem Pole Output:** Supports high-current gate drive for power MOSFETs.  
- **Low Startup Current:** Typically 0.5mA.  

This information is based on FAIRCHILD's documentation for the KA3882C. For exact details, refer to the official datasheet.
