Description and Introduction

Quick-PWM Slave Controller with Driver Disable for Multiphase, DC-DC Converter The MAX1980ETP-T is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Package:** 20-pin TQFN (5mm x 5mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions & Features:**  
- **High Efficiency:** Uses synchronous rectification for improved power conversion.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage approaches the output voltage.  
- **PWM/PFM Mode:** Automatically switches between pulse-width modulation (PWM) and pulse-frequency modulation (PFM) for optimal efficiency across load conditions.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Low Quiescent Current:** 50µA (typical) in PFM mode.  
- **Overcurrent & Thermal Protection:** Built-in safeguards for reliability.  
- **Adjustable Output:** Uses external resistors to set the desired output voltage.  

This IC is commonly used in portable devices, battery-powered systems, and point-of-load (POL) applications.
