Description and Introduction

Quick-PWM Slave Controller with Driver Disable for Multiphase DC-DC Converter The MAX1980ETP is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 30V  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 92%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-Pin TQFN (5mm x 5mm)  

### **Descriptions:**  
The MAX1980ETP is a synchronous buck (step-down) DC-DC converter designed for high-efficiency power conversion in applications requiring a wide input voltage range. It integrates high-side and low-side MOSFETs, reducing external component count. The device supports adjustable output voltage and includes features like soft-start, overcurrent protection, and thermal shutdown.

### **Features:**  
- **Integrated Power MOSFETs** (High-side and low-side)  
- **Adjustable Output Voltage** (1.25V to 30V)  
- **High Efficiency (Up to 92%)**  
- **300kHz Fixed-Frequency PWM Operation**  
- **Soft-Start Function**  
- **Overcurrent and Thermal Protection**  
- **Low Shutdown Current (<10µA)**  
- **Compact 20-Pin TQFN Package**
