Description and Introduction

REGULATING PULSE WIDTH MODULATORS The SG3524P013TR is a pulse width modulator (PWM) controller IC manufactured by STMicroelectronics.  

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Voltage:** 5V (Reference)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** Adjustable (typically up to 300kHz)  
- **Duty Cycle Range:** 0% to 45% (for push-pull configuration)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The SG3524P013TR is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications. It includes an error amplifier, oscillator, PWM comparator, and output drivers.  

### **Features:**  
- **On-Chip 5V Reference Voltage**  
- **Adjustable Oscillator Frequency**  
- **Current Limiting Protection**  
- **Soft-Start Capability**  
- **Dual Alternating Outputs**  
- **Undervoltage Lockout (UVLO)**  

This device is commonly used in switch-mode power supplies, inverters, and motor control circuits.

Application Scenarios & Design Considerations

REGULATING PULSE WIDTH MODULATORS

Alternative Part Number

  • UC3524AN --: Pin-compatible PWM controller from the UC3524 series with equivalent regulating functionality and widely available as a direct replacement.
  • TL494CN --: Industry-standard PWM controller with similar dual-output architecture and voltage-mode operation, commonly used as a functional substitute in power supply designs.
  • KA3524 --: Second-source PWM regulator IC equivalent to the SG3524 family, offering the same control topology and pinout for drop-in use.
