Description and Introduction

Power management for multimedia processors The STW4810CHDR/LF is a power management IC (PMIC) manufactured by STMicroelectronics.  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 18V  
- **Output Voltage:** Adjustable (via external resistors)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** PowerSSO-12  

### **Descriptions:**  
The STW4810CHDR/LF is a synchronous step-down DC-DC converter designed for high-efficiency power conversion in industrial, automotive, and consumer applications. It integrates low-RDS(on) MOSFETs for reduced power loss and supports a wide input voltage range.  

### **Features:**  
- **Integrated Power MOSFETs** for compact design  
- **Adjustable Output Voltage** (0.8V to VIN)  
- **Overcurrent Protection (OCP)** and **Thermal Shutdown**  
- **Soft-Start Function** to limit inrush current  
- **Synchronous Rectification** for improved efficiency  
- **Low Quiescent Current** in light-load conditions  
- **AEC-Q100 Qualified** for automotive applications

Application Scenarios & Design Considerations

Power management for multimedia processors

Alternative Part Number

  • IRF7413TRPBF --: N-channel MOSFET in SO-8 with comparable RDS(on) and voltage rating, widely available and pin-compatible for many switching applications.
  • FDS6680A --: Logic-level N-channel MOSFET in SO-8 offering similar current handling and low on-resistance, suitable drop-in replacement in most circuits.
  • SI4436DY-T1-GE3 --: SO-8 N-channel MOSFET with comparable voltage and current ratings, good alternative when supply of the original is limited.
