Description and Introduction

Voltage Mode PWMs The SG2525AN is a pulse width modulator (PWM) controller manufactured by STMicroelectronics (STM). Below are its key specifications, descriptions, and features:

### **Specifications:**
1. **Supply Voltage (VCC):** 8V to 35V  
2. **Output Current (Sink/Source):** 200mA (peak)  
3. **Oscillator Frequency Range:** 100Hz to 500kHz  
4. **Duty Cycle Range:** 0% to 100% (adjustable)  
5. **Error Amplifier Gain Bandwidth:** 1MHz (typical)  
6. **Reference Voltage (VREF):** 5.1V (±1%)  
7. **Operating Temperature Range:** -25°C to +85°C  
8. **Package:** DIP-16  

### **Descriptions:**
- The SG2525AN is a fixed-frequency PWM controller designed for switching power supply applications.  
- It includes an on-chip oscillator, error amplifier, PWM comparator, and output drivers.  
- It provides soft-start and shutdown control features.  
- Suitable for push-pull, half-bridge, and full-bridge converter topologies.  

### **Features:**
1. **Precision Reference:** 5.1V with ±1% accuracy.  
2. **Adjustable Dead-Time Control:** Prevents shoot-through in power switches.  
3. **Soft-Start Function:** Gradually increases duty cycle to reduce inrush current.  
4. **Synchronization Capability:** Allows external clock synchronization.  
5. **Dual Output Drivers:** Supports totem-pole or parallel configurations.  
6. **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
7. **Error Amplifier:** High-gain, wide-bandwidth for feedback control.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to STMicroelectronics' official documentation.
