Description and Introduction

8 PWM 200 KHz Sync Contr in a 8-Pin SOIC(NB) package The IRU3037CS is a step-down DC-DC converter IC manufactured by IR (International Rectifier). Below are the key specifications, descriptions, and features based on available data:

### **Manufacturer:**  
International Rectifier (IR)  

### **Part Number:**  
IRU3037CS  

### **Description:**  
The IRU3037CS is a synchronous buck PWM controller designed for high-efficiency DC-DC voltage regulation applications. It is commonly used in power supply designs for computing, networking, and industrial systems.  

### **Key Features:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Up to 600 kHz  
- **Synchronous Rectification:** Improves efficiency by reducing power loss  
- **PWM Control:** Voltage-mode control architecture  
- **Protection Features:**  
  - Overcurrent protection (OCP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
- **Package:** SOIC-16  

### **Applications:**  
- Point-of-load (POL) converters  
- Distributed power systems  
- Networking and telecom equipment  
- Industrial power supplies  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics, refer to the official IRU3037CS datasheet.

Application Scenarios & Design Considerations

8 PWM 200 KHz Sync Contr in a 8-Pin SOIC(NB) package

Alternative Part Number

  • LM3489MM --: Pin-compatible synchronous buck controller with similar voltage-mode architecture and SOIC-8 package, widely available and well documented.
  • AP3581MP --: Single-phase synchronous buck PWM controller in an 8-pin package with comparable input range and gate drive, suitable as a functional drop-in.
  • ISL6545CBZ --: Low-cost synchronous buck controller with similar feedback and soft-start behavior, offering a different series naming for easy distinction.
