Description and Introduction

Regulating Pulse-Width Modulators The SG3524DR is a pulse width modulation (PWM) controller IC manufactured by LINFINITY. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Type:** PWM Controller  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Frequency Range:** Up to 300 kHz  
- **Supply Voltage (VCC):** 8V to 40V  
- **Output Current (Source/Sink):** 100mA (per channel)  
- **Duty Cycle Range:** 0% to 45% (adjustable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**
- The SG3524DR is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications.  
- It includes an on-chip oscillator, error amplifier, PWM comparator, and dual alternating output drivers.  
- Suitable for push-pull and single-ended configurations.  

### **Features:**
- **Adjustable Frequency:** Set via external resistor and capacitor.  
- **Dual Output Drivers:** Allows for push-pull or single-ended operation.  
- **Current Limiting:** Built-in protection against overcurrent conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Error Amplifier:** Provides precise voltage regulation.
