Description and Introduction

High-Side MOSFET Driver for HB LED Drivers and DC-DC Applications The MAX15054AUT+T is a high-efficiency, synchronous step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 60V  
- **Output Voltage Range:** 0.9V to 90% of VIN  
- **Output Current:** Up to 4A  
- **Switching Frequency:** Adjustable (100kHz to 2.2MHz)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin TDFN (3mm x 3mm)  

### **Descriptions:**  
The MAX15054AUT+T is a synchronous buck converter designed for high-voltage industrial, automotive, and telecom applications. It integrates high-side and low-side MOSFETs, reducing external component count. The device supports adjustable frequency and features cycle-by-cycle current limiting, thermal shutdown, and soft-start functionality.

### **Features:**  
- **Wide Input Voltage Range (4.5V–60V)**  
- **Integrated Power MOSFETs**  
- **Adjustable Switching Frequency (100kHz–2.2MHz)**  
- **Programmable Soft-Start**  
- **Cycle-by-Cycle Current Limit**  
- **Thermal Shutdown Protection**  
- **Low Quiescent Current (40µA in Shutdown)**  
- **Forced-PWM and Skip Modes**  
- **Precision Enable Input**  

This device is suitable for applications requiring high efficiency and compact power solutions, such as industrial systems, automotive electronics, and telecom infrastructure.
