Description and Introduction

Multi-Topology (buck, boost, sepic) High Frequency DC/DC Controller 16-TSSOP -40 to 85 The TPS43000PWRG4 is a synchronous step-down DC-DC controller manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 52V  
- **Output Voltage Range:** 0.8V to 90% of VIN  
- **Switching Frequency:** Adjustable from 50kHz to 1MHz  
- **Maximum Duty Cycle:** 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-pin TSSOP (PWR)  

### **Descriptions:**  
The TPS43000PWRG4 is a high-performance, wide-input voltage synchronous buck controller designed for industrial, automotive, and telecom applications. It supports both N-channel MOSFETs and integrates features for efficient power conversion.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 52V input.  
- **Adjustable Frequency:** Allows optimization for efficiency or size.  
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  
- **Programmable Soft Start:** Prevents inrush current.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **External Compensation:** Provides flexibility in loop stability design.  

This information is based on the TI datasheet for the TPS43000PWRG4.
