Description and Introduction

Silicon Epitaxial Planar The TPS843 is a switching regulator IC manufactured by Toshiba. Below are the factual specifications, descriptions, and features based on available knowledge:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable (typically 0.8V to 5.5V)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** HSOP-8  

### **Descriptions:**  
- The TPS843 is a step-down (buck) DC-DC converter with synchronous rectification.  
- It integrates a high-side and low-side MOSFET for efficient power conversion.  
- Designed for applications requiring high efficiency and compact power solutions.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Over-Current Protection (OCP):** Safeguards against excessive load current.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.
