Description and Introduction

SMPS Controller The KA3882CDTF is a switching regulator controller manufactured by Fairchild Semiconductor. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** FAIRCHILD  
- **Type:** Switching Regulator Controller  
- **Package:** TO-220F (5-Lead)  
- **Input Voltage Range:** Up to 30V  
- **Output Voltage:** Adjustable  
- **Switching Frequency:** Fixed (typically 52 kHz)  
- **Operating Temperature Range:** -25°C to +85°C  
- **Duty Cycle:** Adjustable  
- **Current Limiting:** Yes  
- **Start-Up Current:** Low (typically 0.5 mA)  

### **Descriptions:**  
- The KA3882CDTF is a high-performance PWM controller designed for DC-DC converter applications.  
- It is optimized for offline and DC-to-DC power supplies with minimal external components.  
- Features include an internal temperature-compensated reference, current sensing, and a high-gain error amplifier.  

### **Features:**  
- **PWM Control:** Precise duty cycle regulation.  
- **Undervoltage Lockout (UVLO):** Ensures proper start-up and shutdown.  
- **Soft-Start Capability:** Reduces inrush current.  
- **Error Amplifier:** High gain for stable feedback control.  
- **Current Limiting:** Protects against overloads.  
- **Low Standby Current:** Improves efficiency in standby mode.  
- **Totem Pole Output:** Capable of driving power MOSFETs directly.  

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