Description and Introduction

Automotive Grade 3-75V Wide Vin, Current Mode Non-Synchronous Buck-Boost Controller 20-HTSSOP -40 to 125 The **LM5118Q1MHX/NOPB** is a synchronous buck controller manufactured by **Texas Instruments (NS)**. Below are the key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 75V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Driver Output Current:** 2A (source/sink)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-Pin HTSSOP (PowerPAD™)  
- **Control Method:** Peak Current Mode Control  
- **Qualification:** AEC-Q100 (Automotive Grade)  

### **Descriptions:**  
- Designed for high-voltage DC-DC buck converter applications.  
- Supports synchronous rectification for improved efficiency.  
- Includes adaptive dead-time control to minimize body diode conduction.  
- Features cycle-by-cycle current limiting and hiccup-mode fault protection.  

### **Features:**  
- **Wide Input Voltage Range (4.5V–75V)** – Suitable for automotive and industrial applications.  
- **Adjustable Frequency (100kHz–1MHz)** – Allows optimization for efficiency and component size.  
- **Integrated High-Side & Low-Side Gate Drivers** – Reduces external component count.  
- **Programmable Soft-Start** – Prevents inrush current during startup.  
- **UVLO (Undervoltage Lockout) & Thermal Shutdown** – Enhances system protection.  
- **AEC-Q100 Qualified** – Meets automotive reliability standards.
