Description and Introduction

REGULATING PULSE WIDTH MODULATOR The SG3526 is a pulse width modulation (PWM) controller IC designed for power supply applications. Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
- The SG3526 is manufactured by **ON Semiconductor** (formerly part of **Microsemi** and **Silicon General**).  

### **Specifications:**  
- **Input Voltage Range:** 8V to 35V  
- **Output Current:** Up to 200mA (sink/source)  
- **Operating Frequency Range:** Adjustable (typically up to 500kHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 1MHz (typical)  
- **Reference Voltage:** 5.1V (±1%)  
- **Soft-Start Capability:** Yes  
- **Shutdown Pin:** Available for external control  
- **Package Options:** DIP-16, SOIC-16  

### **Descriptions:**  
- The SG3526 is a voltage-mode PWM controller used in switch-mode power supplies (SMPS), DC-DC converters, and inverters.  
- It includes an error amplifier, oscillator, PWM comparator, and output drivers.  
- The IC supports push-pull and single-ended configurations.  
- It features under-voltage lockout (UVLO) protection to prevent operation at low input voltages.  

### **Features:**  
- **Precision Reference Voltage (5.1V)**  
- **Adjustable Dead-Time Control**  
- **Synchronizable Oscillator**  
- **Current Limiting Protection**  
- **Soft-Start Function**  
- **Low Standby Current**  
- **Thermal Shutdown Protection**  

These details are based on the manufacturer's datasheet and technical documentation.
