Description and Introduction

SMPS Controller Certainly! Here is the factual information about the **KA3883 C** manufactured by **FAIRCHILD** (Fairchild Semiconductor):  

### **Specifications:**  
- **Manufacturer:** Fairchild Semiconductor  
- **Part Number:** KA3883 C  
- **Type:** Switching Regulator Controller (PWM Controller)  
- **Package:** SOP-8 (Small Outline Package)  
- **Input Voltage Range:** Typically up to 30V  
- **Switching Frequency:** Adjustable (commonly up to 500 kHz)  
- **Output Drive:** Totem-pole output for driving power MOSFETs  
- **Duty Cycle:** Adjustable (typically up to 100%)  
- **Operating Temperature Range:** -25°C to +85°C (or similar, depending on variant)  

### **Descriptions:**  
- The **KA3883 C** is a pulse-width modulation (PWM) controller IC designed for switch-mode power supply (SMPS) applications.  
- It provides precise control over power conversion in DC-DC converters, offline power supplies, and other power management circuits.  
- The device includes features like under-voltage lockout (UVLO), soft-start, and current limiting for improved reliability.  

### **Features:**  
- **PWM Control:** Adjustable duty cycle for efficient power regulation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within safe voltage limits.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Current Limiting:** Protects against overload conditions.  
- **High Output Drive:** Capable of driving power MOSFETs directly.  
- **Low Standby Power Consumption:** Optimized for energy efficiency.  
- **Adjustable Oscillator Frequency:** Allows flexibility in design.
