Description and Introduction

5 Bit Prog SynchBuck CIC w/3 LDO Controllers w/FET in a 28-Pin SOIC(WB) package The IRU3021MCW is a step-down DC-DC converter manufactured by IOR (Integrated Operational Research). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage Range:** Adjustable from 0.8V to 24V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOP-8  

### **Descriptions:**  
- The IRU3021MCW is a synchronous buck converter designed for high-efficiency voltage regulation.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- Suitable for industrial, automotive, and consumer electronics applications.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 36V input.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Overcurrent Protection:** Prevents damage from excessive load conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Compact Design:** SOP-8 package for space-constrained applications.
