Description and Introduction

Pulse Width Modulator Control Circuit The SG3525ANG is a pulse width modulation (PWM) controller IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Output Configuration:** Dual, complementary outputs  
- **Topology:** Push-Pull, Half-Bridge, Full-Bridge  
- **Switching Frequency:** Up to 400 kHz  
- **Operating Voltage Range:** 8V to 35V  
- **Output Current:** 100 mA (sink/source per channel)  
- **Duty Cycle Range:** 0% to 49% (adjustable)  
- **Reference Voltage:** 5.1V (±1%)  
- **Soft-Start Function:** Yes  
- **Undervoltage Lockout (UVLO):** Yes  
- **Error Amplifier:** Built-in  
- **Package:** PDIP-16  

### **Descriptions:**  
The SG3525ANG is a voltage-mode PWM controller designed for DC-DC converters and power supply applications. It features an adjustable oscillator, error amplifier, and soft-start functionality, making it suitable for high-efficiency power conversion.  

### **Features:**  
- **Precision Reference Voltage:** 5.1V with tight tolerance  
- **Adjustable Dead-Time Control:** Prevents shoot-through in bridge circuits  
- **Synchronization Capability:** Allows multiple ICs to sync to a master clock  
- **Current Limiting:** Supports external current sensing  
- **Low Standby Current:** Typically 8 mA  
- **Temperature Stability:** Designed for industrial applications  

This IC is commonly used in switch-mode power supplies (SMPS), inverters, and motor control circuits.
