Description and Introduction

4 Channel Multiphase Buck DC/DC Controller with Tri-state The TPS40091 is a synchronous buck controller manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.7V to 5.5V  
- **Switching Frequency:** Adjustable (100kHz to 600kHz)  
- **Maximum Duty Cycle:** 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** 20-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
The TPS40091 is a high-performance, wide-input-voltage synchronous buck controller designed for point-of-load DC-DC conversion. It supports N-channel MOSFETs and provides high efficiency with adaptive gate drive timing.  

### **Features:**  
- **Adaptive Non-Overlapping Gate Drives:** Reduces shoot-through current.  
- **Programmable Soft Start:** Limits inrush current.  
- **Voltage Feed-Forward Compensation:** Improves transient response.  
- **Power Good Output:** Monitors output voltage status.  
- **Synchronization Capability:** Can sync to an external clock.  
- **Overcurrent Protection:** Uses MOSFET RDS(on) sensing.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup.  

This information is sourced from TI's official documentation for the TPS40091.
