Description and Introduction

Multi-Topology (buck, boost, sepic) High Frequency DC/DC Controller The TPS43000PWR is a synchronous buck-boost DC/DC controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.9V to 36V  
- **Output Voltage Range:** Adjustable from 1.23V to 36V  
- **Switching Frequency:** 100kHz to 2.5MHz (adjustable)  
- **Maximum Output Current:** Up to 5A (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-pin TSSOP (PWR)  

### **Descriptions:**  
The TPS43000PWR is a high-efficiency, wide-input-voltage DC/DC controller designed for applications requiring both step-up (boost) and step-down (buck) conversion. It supports synchronous rectification for improved efficiency and can operate in buck, boost, or buck-boost modes.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 2.9V to 36V input.  
- **Adjustable Output Voltage:** Configurable from 1.23V to 36V.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Programmable Switching Frequency:** Adjustable from 100kHz to 2.5MHz.  
- **Soft-Start Function:** Prevents inrush current.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Overcurrent and Thermal Protection:** Enhances system reliability.  
- **Low Quiescent Current:** 1.5mA typical.  

This device is commonly used in industrial, automotive, and battery-powered applications.
