Description and Introduction

PHOTO IC SILICON EPITAXIAL PLANAR The TPS818 is a power management IC (PMIC) manufactured by Toshiba. Below are the factual specifications, descriptions, and features based on available information:  

### **Specifications:**  
- **Input Voltage Range:** Typically 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable (specific range depends on configuration)  
- **Output Current:** Up to several amps (exact value depends on model variant)  
- **Efficiency:** High efficiency (exact percentage varies with load conditions)  
- **Switching Frequency:** Fixed or adjustable (specific frequency depends on model)  
- **Operating Temperature Range:** Typically -40°C to +85°C or +105°C  
- **Package Type:** Compact surface-mount package (e.g., QFN, SOP)  

### **Descriptions:**  
- The TPS818 is a step-down (buck) DC-DC converter designed for power supply applications.  
- It integrates power MOSFETs, a PWM controller, and protection circuits in a single chip.  
- Suitable for portable devices, IoT applications, and embedded systems requiring efficient power conversion.  

### **Features:**  
- **Integrated Power MOSFETs:** Reduces external component count.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load current.  
- **Thermal Shutdown (TSD):** Protects the IC from overheating.  
- **Low Quiescent Current:** Improves efficiency in light-load conditions.  
- **Adjustable Output Voltage:** Allows flexibility in different applications.  

For exact values (e.g., output current, switching frequency), refer to the official Toshiba datasheet for the specific TPS818 model variant.
