Description and Introduction

REGULATING PULSE WIDTH MODULATOR The part **SG2524** is a **PWM Controller IC** manufactured by **Texas Instruments (TI)**.  

### **Specifications:**  
- **Type:** Voltage Mode PWM Controller  
- **Input Voltage Range:** 8V to 40V  
- **Output Voltage:** Adjustable (depends on external components)  
- **Switching Frequency:** Up to 300kHz (adjustable with external components)  
- **Duty Cycle Range:** 0% to 90% (typical)  
- **Output Current:** 100mA (source/sink)  
- **Reference Voltage:** 5V (±1%)  
- **Operating Temperature Range:** -25°C to +85°C  
- **Package:** 16-Pin DIP (Dual Inline Package)  

### **Descriptions & Features:**  
- Designed for **switch-mode power supply (SMPS) applications**  
- **Voltage-mode control architecture**  
- **On-chip oscillator** with adjustable frequency  
- **Error amplifier** for feedback control  
- **Soft-start capability** to reduce inrush current  
- **Pulse-by-pulse current limiting** for protection  
- **Undervoltage lockout (UVLO)** to prevent malfunction at low input voltages  
- **Totem-pole output stage** for driving power MOSFETs or transistors  
- **Widely used in DC-DC converters, inverters, and power supplies**  

This IC is commonly used in **industrial, automotive, and consumer electronics** for efficient power conversion.

Application Scenarios & Design Considerations

REGULATING PULSE WIDTH MODULATOR

Alternative Part Number

  • UC3524AN --: Pin-compatible regulating pulse width modulator with same function and voltage range, widely available and directly interchangeable in most designs.
  • TL494CN --: Very common PWM controller with similar dual-output architecture and supply range; requires minor circuit adjustment but is a cost-effective, well-stocked alternative.
  • SG3524N --: Equivalent regulating PWM controller from a different series and manufacturer, offering the same core functionality as a second-source option.
  • UC3524N --: Industry-standard regulating pulse width modulator with the same function and pinout as the SG2524, widely available and well documented.
