Description and Introduction

Low-Output-Voltage / 800mA / PWM Step-Down DC-DC Converters The MAX1928EUB15 is a voltage regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1928EUB15  
- **Package Type:** μMAX (10-pin)  
- **Output Voltage:** 1.5V (fixed)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 120mV (typical at 100mA load)  
- **Quiescent Current:** 50μA (typical)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX1928EUB15 is a high-efficiency, step-down DC-DC converter that provides a fixed 1.5V output from an input voltage range of 2.5V to 5.5V. It is designed for low-power applications requiring high efficiency and small footprint. The device operates at a high switching frequency, allowing the use of small external components.

### **Features:**
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Low Dropout:** 120mV typical dropout at 100mA load.  
- **Low Quiescent Current:** 50μA typical, improving battery life.  
- **Fixed Output Voltage:** 1.5V preset output.  
- **Small Footprint:** μMAX package (10-pin) saves board space.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Short-Circuit Protection:** Safeguards the device under fault conditions.  

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