Description and Introduction

8-Pin High Frequency 4-Amp Sink Synchronous MOSFET Driver The TPS28225 is a high-frequency synchronous buck MOSFET driver manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range (VDD):** 4.5V to 14V  
- **Output Drive Voltage (BOOT to PHASE):** 4.5V to 14V  
- **Peak Source Current:** 2.5A  
- **Peak Sink Current:** 4.5A  
- **Propagation Delay (Rise/Fall):** 25ns (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** 6-Pin SOT-23 (DBV)  

### **Descriptions:**  
- The TPS28225 is designed to drive both high-side and low-side N-channel MOSFETs in synchronous buck converters.  
- It features adaptive dead-time control to prevent shoot-through and improve efficiency.  
- The device operates at high frequencies, making it suitable for compact power supply designs.  

### **Features:**  
- **Adaptive Dead-Time Control:** Minimizes body diode conduction losses.  
- **Fast Propagation Delays:** Ensures high-frequency operation.  
- **High Drive Current:** 2.5A source / 4.5A sink for quick MOSFET switching.  
- **Wide Input Voltage Range:** Supports 4.5V to 14V operation.  
- **Low Power Consumption:** Optimized for efficiency.  
- **Small Footprint:** Available in a compact 6-pin SOT-23 package.
