Description and Introduction

Low-Noise Step-Up DC-DC Converters The MAX1790EUA+ is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1790EUA+  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (2.5V to 5.5V)  
- **Output Current:** Up to 150mA (at 3.3V output)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Package:** 8-pin μMAX (MSOP)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX1790EUA+ is a high-efficiency, low-power, step-up DC-DC converter designed for battery-powered applications. It is optimized for low-input-voltage operation, making it suitable for single-cell or dual-cell battery systems. The device integrates a power switch and provides a regulated output voltage with minimal external components.

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **High Efficiency:** Up to 90% efficiency for extended battery life.  
- **Low Quiescent Current:** 12µA (typical) in shutdown mode.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Prevents damage under fault conditions.  
- **Compact Package:** 8-pin μMAX (MSOP) for space-constrained designs.  

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