Description and Introduction

Dual-Phase, Quick-PWM Controllers for Programmable CPU Core Power Supplies The MAX1545ETL is a step-down DC-DC converter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Manufacturer:**  
MAXIM (Maxim Integrated)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 40-Pin TQFN (Thin Quad Flat No-Lead)  
- **Topology:** Synchronous Buck Converter  

### **Descriptions:**  
The MAX1545ETL is a high-efficiency, synchronous step-down DC-DC converter designed for applications requiring high current and wide input voltage ranges. It integrates low-side and high-side MOSFETs, reducing external component count. The device supports adjustable output voltage and switching frequency, making it suitable for various power supply designs.  

### **Features:**  
- **Integrated Power MOSFETs** (High-side and Low-side)  
- **Adjustable Output Voltage** (0.8V to 5.5V)  
- **Programmable Switching Frequency** (300kHz to 1MHz)  
- **Peak Current-Mode Control** for fast transient response  
- **Soft-Start and Short-Circuit Protection**  
- **Power-Good Output** for system monitoring  
- **Low Quiescent Current** in shutdown mode  
- **Thermal Shutdown Protection**  

This information is strictly based on the manufacturer's datasheet and technical documentation.
