Description and Introduction

Synchronous Buck PWM Controller with NMOS LDO Controller The TPS5110PW is a synchronous buck controller manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.9V  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Supports up to 10A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TSSOP (PW)  

### **Descriptions:**  
- The TPS5110PW is a high-efficiency synchronous buck controller designed for DC-DC voltage regulation.  
- It drives external N-channel MOSFETs to provide step-down conversion.  
- Suitable for applications requiring high current and efficiency, such as notebook computers and embedded systems.  

### **Features:**  
- **Integrated 5V LDO** for gate drive and bias supply.  
- **Adjustable Soft-Start** to limit inrush current.  
- **Overcurrent Protection (OCP)** with hiccup mode.  
- **Undervoltage Lockout (UVLO)** for input voltage monitoring.  
- **Power-Good (PG) Output** for system monitoring.  
- **Synchronous Rectification** for improved efficiency.
