Description and Introduction

Power Factor Correction Controller The KA7526 is a Pulse Width Modulation (PWM) controller IC manufactured by Fairchild Semiconductor. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Input Voltage Range:** Typically operates with a wide input voltage range, suitable for power supply applications.  
- **Output Frequency:** Adjustable, often in the range of tens to hundreds of kilohertz.  
- **Duty Cycle Range:** Adjustable, typically up to 90% or higher.  
- **Operating Temperature Range:** Industrial-grade temperature range (e.g., -40°C to +85°C).  
- **Package Type:** Commonly available in DIP (Dual In-line Package) or SOIC (Small Outline IC) packages.  

### **Descriptions:**  
- The KA7526 is designed for switch-mode power supply (SMPS) applications.  
- It provides precise PWM control for regulating DC-DC converters, inverters, and other power management systems.  
- The IC includes built-in protection features such as over-voltage protection (OVP) and under-voltage lockout (UVLO).  

### **Features:**  
- **Adjustable Frequency:** Allows flexibility in power supply design.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Error Amplifier:** Ensures stable output regulation.  
- **Current Limiting:** Protects against excessive load conditions.  
- **Low Standby Power Consumption:** Improves efficiency in standby modes.  

For exact electrical characteristics and application circuits, refer to the official Fairchild Semiconductor datasheet.

Description and Introduction

Power Factor Correction Controller The KA7526 is a switching regulator controller IC manufactured by Fairchild Semiconductor (FAI).  

### **Specifications:**  
- **Type:** Switching Regulator Controller  
- **Topology:** Step-up (Boost), Step-down (Buck), or Flyback  
- **Operating Voltage Range:** Typically 8V to 40V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Fixed or adjustable (depending on configuration)  
- **Duty Cycle:** Adjustable for PWM control  
- **Protection Features:** Overcurrent protection (OCP), thermal shutdown  

### **Descriptions:**  
The KA7526 is designed for DC-DC converter applications, providing efficient power conversion in various configurations. It includes an internal reference voltage, error amplifier, and PWM comparator for precise regulation.  

### **Features:**  
- **Wide Input Voltage Range** (suitable for automotive and industrial applications)  
- **High Efficiency** due to PWM control  
- **Low Standby Current**  
- **Built-in Soft-Start Function** (prevents inrush current)  
- **External Synchronization Capability** (for noise-sensitive applications)  

For exact electrical characteristics, refer to the official Fairchild (FAI) datasheet.
