Description and Introduction

5V/12V/15V or Adjustable, High-Efficiency Low-IQ, Step-Up DC-DC Controllers The MAX771CSA+ 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 Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Category:** Power Management IC  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable (up to 5.5V) or fixed (3.3V or 5V)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 95%  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**
The MAX771CSA+ is a high-efficiency, low-power, step-up DC-DC converter designed for battery-powered applications. It is optimized for low-input voltage conditions, making it suitable for single-cell or dual-cell battery systems. The device includes an internal power MOSFET, reducing external component count.  

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Adjustable or Fixed Output:** Supports 3.3V or 5V fixed output or adjustable via external resistors.  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Low Quiescent Current:** 50µA typical.  
- **Internal Power MOSFET:** Simplifies design and reduces external components.  
- **Short-Circuit Protection:** Includes foldback current limiting.  
- **Small Footprint:** Available in an 8-pin SOIC package.
