- Audio/video equipment  

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

Application Scenarios & Design Considerations

5 Bit Programmable Synchronous Buck Controller IC in a 20-Pin SOIC(WB) package

Alternative Part Number

  • ISL6520ACBZ --: Single synchronous buck PWM controller in SOIC-8, functionally similar to the IRU3011CW and widely available; Renesas/Intersil is the successor to IR's analog portfolio.
  • TPS5210PWP --: Synchronous buck controller with comparable voltage-mode control and gate drive, suitable as a drop-in functional substitute in many designs.
  • LTC3728EG --: Dual-phase synchronous buck controller offering similar control functionality and robust gate drive, usable as an alternative with minor layout changes.

Description and Introduction

5 Bit Programmable Synchronous Buck Controller IC in a 20-Pin SOIC(WB) package The IRU3011CW is a voltage regulator module manufactured by IOR (International Rectifier). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 14V  
- **Output Voltage:** Adjustable (typically 0.8V to 5.5V)  
- **Output Current:** Up to 30A  
- **Efficiency:** Up to 95%  
- **Switching Frequency:** 300kHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 10mm x 14mm x 2.8mm PQFN  

### **Descriptions:**  
- The IRU3011CW is a synchronous buck regulator designed for high-performance power supply applications.  
- It integrates MOSFETs and control circuitry to provide a compact, high-efficiency solution.  
- Suitable for point-of-load (POL) regulation in computing, networking, and telecommunications equipment.  

### **Features:**  
- **Integrated Power MOSFETs** – Reduces external component count.  
- **Adjustable Output Voltage** – Configurable via external resistors.  
- **Overcurrent & Overtemperature Protection** – Enhances system reliability.  
- **Programmable Soft-Start** – Prevents inrush current issues.  
- **Remote Sense Capability** – Improves voltage regulation accuracy.
