Description and Introduction

REGULATING PULSE WIDTH MODULATOR The SG3526DW is a pulse width modulation (PWM) controller IC manufactured by LINFINITY. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** LINFINITY  
- **Package:** SOIC-16 (DW suffix indicates wide-body SOIC package)  
- **Operating Voltage Range:** Typically 8V to 35V  
- **Output Current:** Up to 200mA (sink/source per channel)  
- **Switching Frequency:** Adjustable (typically up to 500kHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** Typically 1MHz  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The SG3526DW is a high-performance PWM controller designed for power supply applications.  
- It includes an onboard oscillator, error amplifier, PWM comparator, and dual alternating outputs for push-pull or half-bridge configurations.  
- Suitable for DC-DC converters, inverters, and SMPS (Switched-Mode Power Supplies).  

### **Features:**  
- **Dual Outputs:** Alternating outputs for push-pull or half-bridge topologies.  
- **Adjustable Frequency:** External resistor and capacitor allow frequency programming.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Current Limiting:** Protects against overload conditions.  
- **Synchronization Capability:** Can be synchronized to an external clock.  
- **Error Amplifier:** High-gain op-amp for feedback loop control.  

This information is based solely on the manufacturer's datasheet and technical documentation.

- **Error Amplifier:** Includes an internal error amplifier for feedback control  
- **Protection Features:** Under-voltage lockout (UVLO), over-current protection  

### **Descriptions:**  
The SG3526DW is a fixed-frequency PWM controller designed for power supply applications. It provides precise voltage regulation and supports push-pull or single-ended configurations. The IC includes an oscillator, error amplifier, PWM comparator, and output drivers.  

### **Features:**  
- Adjustable dead-time control  
- Synchronization capability for multiple ICs  
- Dual alternating outputs for push-pull topologies  
- Low standby current  
- Thermal shutdown protection  

This IC is commonly used in DC-DC converters, inverters, and switch-mode power supplies (SMPS).
