Description and Introduction

5V/12V/15V or Adjustable, High-Efficiency Low-IQ, Step-Up DC-DC Controllers The MAX770CSA+T is a step-up DC-DC switching regulator manufactured by Maxim Integrated.  

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable from 2V to 5.5V (fixed 3.3V or 5V versions available)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC  
- **Low Battery Detection:** Adjustable threshold  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX770CSA+T is a low-power, step-up DC-DC converter designed for battery-powered applications. It features a unique control scheme that allows operation from very low input voltages (down to 0.7V), making it suitable for single-cell or dual-cell battery systems. The device includes an internal power switch, simplifying design and reducing external component count.  

### **Features:**  
- **Wide Input Voltage Range:** Operates from 0.7V to 5.5V  
- **Adjustable/Fixed Output Voltage:** Supports 3.3V or 5V fixed or adjustable output  
- **Low Quiescent Current:** 60µA typical  
- **Internal Power MOSFET:** Eliminates need for an external switch  
- **Low-Battery Detector:** Adjustable threshold for battery monitoring  
- **Small Footprint:** 8-pin SOIC package  
- **Soft-Start:** Reduces inrush current during startup  

This device is commonly used in portable electronics, battery-powered systems, and energy-harvesting applications.
