Description and Introduction

Regulating Pulse Width Modulators The SG3527AJ is a pulse width modulation (PWM) controller IC manufactured by various semiconductor companies, including STMicroelectronics and ON Semiconductor. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** Typically operates from 8V to 35V.  
- **Output Current:** Up to 200mA (sink/source per channel).  
- **Oscillator Frequency Range:** Adjustable from 100Hz to 400kHz.  
- **Duty Cycle Range:** Adjustable from 0% to 100%.  
- **Reference Voltage Output:** 5.1V (±1%).  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade).  
- **Package Type:** 16-pin DIP (Dual In-line Package) or SOIC (Surface Mount).  

### **Descriptions:**  
- The SG3527AJ is a fixed-frequency PWM controller designed for switch-mode power supply (SMPS) applications.  
- It features two alternating outputs for push-pull or half-bridge converter topologies.  
- Includes an onboard error amplifier, oscillator, soft-start control, and shutdown functionality.  

### **Features:**  
- **Dual Output Drivers:** Alternating outputs for push-pull configurations.  
- **Adjustable Dead-Time Control:** Prevents shoot-through in power stages.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Error Amplifier:** Provides feedback loop regulation.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Shutdown Pin:** Provides immediate disable function.  

This information is based on the manufacturer's datasheet for the SG3527AJ PWM controller.
