Description and Introduction

REGULATING PULSE WIDTH MODULATOR The SG3524BJ is a pulse width modulation (PWM) controller IC manufactured by various semiconductor companies, including Texas Instruments and ON Semiconductor. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Voltage:** Adjustable (depends on external components)  
- **Operating Frequency Range:** 100Hz to 350kHz (adjustable via external timing components)  
- **Output Current:** Up to 100mA (per output)  
- **Duty Cycle Range:** 0% to 45% (for push-pull operation)  
- **Reference Voltage:** 5V (±1%)  
- **Oscillator Frequency Adjustment:** Via external resistor (RT) and capacitor (CT)  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  
- **Package Type:** DIP-16 (Dual Inline Package)  

### **Descriptions:**  
- The SG3524BJ is a fixed-frequency PWM controller primarily used in DC-DC converters, inverters, and power supply applications.  
- It includes an error amplifier, oscillator, PWM comparator, latch, and dual alternating output drivers.  
- The device is designed for push-pull or single-ended power supply topologies.  
- It provides voltage regulation through feedback control.  

### **Features:**  
- **Complete PWM Control Circuitry**  
- **On-Chip 5V Reference Voltage**  
- **Adjustable Dead-Time Control**  
- **Dual Source/Sink Output Drivers**  
- **Current Limiting and Shutdown Protection**  
- **Synchronization Capability for Multiple ICs**  
- **Low Standby Current (Typically 8mA)**

Application Scenarios & Design Considerations

REGULATING PULSE WIDTH MODULATOR

Alternative Part Number

  • UC3524AJ --: Same regulating pulse width modulator function with identical pinout and voltage reference, widely available and a direct functional replacement.
  • LM3524J --: Classic 3524-series PWM controller in a ceramic DIP package, pin-compatible and electrically equivalent to the SG3524BJ.
  • CA3524E --: Equivalent 3524-type switching regulator controller with matching control circuitry, suitable as a drop-in alternative.
  • TL494CJ --: Popular PWM controller with similar dual-output architecture and voltage reference, commonly used as a functional substitute where exact pinout matching is not critical.
  • LM3524DJ --: Direct equivalent regulating PWM controller in the same family, offering comparable electrical characteristics and a well-known drop-in option.
