Description and Introduction

500mA, Low-Voltage Linear Regulator in Tiny QFN The MAX1935ETA+T is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated (now part of Analog Devices)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 28V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin TDFN (3mm x 3mm)  

### **Descriptions:**  
- The MAX1935ETA+T is a synchronous step-down DC-DC converter with an integrated high-side and low-side MOSFET.  
- It provides a fixed-frequency PWM operation for stable output regulation.  
- The device includes features like soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Integrated Synchronous Rectifier:** Improves efficiency by eliminating the need for an external Schottky diode.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Low Quiescent Current:** Typically 60µA in shutdown mode.  
- **Overcurrent and Thermal Protection:** Enhances reliability under fault conditions.  
- **Small Footprint:** Suitable for space-constrained applications.  

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