Description and Introduction

4 Channel Multiphase Buck DC/DC Controller The TPS40090PW is a synchronous buck controller manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.7V to 5.5V (adjustable)  
- **Switching Frequency:** 50kHz to 1MHz (adjustable)  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-pin TSSOP (PW)  

### **Descriptions:**  
The TPS40090PW is a high-performance synchronous buck controller designed for step-down DC/DC conversion applications. It supports a wide input voltage range, making it suitable for various power supply designs. The device integrates high-side and low-side MOSFET drivers, reducing external component count.  

### **Features:**  
- **Adjustable Output Voltage:** Via external resistor divider  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and size  
- **Synchronous Rectification:** Improves efficiency by reducing power loss  
- **Soft-Start:** Reduces inrush current during startup  
- **Overcurrent Protection (OCP):** Prevents damage during fault conditions  
- **Thermal Shutdown:** Protects the device from overheating  
- **Power Good Indicator:** Monitors output voltage status  
- **Low Quiescent Current:** Enhances efficiency in light-load conditions
