Description and Introduction

Voltage Mode PWMs The SG3525ADW is a pulse width modulation (PWM) controller IC manufactured by Microsemi Corporation (MSC). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Microsemi Corporation (MSC)  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Supply Voltage (Vcc):** 8V to 35V  
- **Output Current (Source/Sink):** 200mA (Peak)  
- **Oscillator Frequency Range:** 100Hz to 500kHz  
- **Duty Cycle Range:** 0% to 49% (adjustable)  
- **Reference Voltage (Vref):** 5.1V (±1%)  
- **Soft-Start Capability:** Yes  
- **Shutdown Pin:** Active high or low (programmable)  
- **Error Amplifier Gain Bandwidth:** 2MHz (Typical)  

### **Descriptions:**  
The SG3525ADW is a high-performance PWM controller designed for switching power supply applications. It provides precise voltage regulation and includes features such as soft-start, shutdown control, and an adjustable oscillator frequency. The device is commonly used in DC-DC converters, inverters, and motor control circuits.  

### **Features:**  
- **PWM Control:** Adjustable duty cycle with push-pull or single-ended output configuration.  
- **Error Amplifier:** High-gain op-amp for feedback loop control.  
- **Soft-Start Function:** Prevents high inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within supply voltage limits.  
- **Sync Capability:** Allows synchronization with an external clock.  
- **Dead-Time Control:** Adjustable to prevent shoot-through in half-bridge or full-bridge topologies.  
- **Low Standby Current:** Typically 8mA (when disabled).  

This information is based on the manufacturer's datasheet and technical specifications.
