Description and Introduction

5V/12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controllers The MAX772CSA is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

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

### **Specifications:**  
- **Part Number:** MAX772CSA  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage:** Adjustable or Fixed (depending on configuration)  
- **Output Current:** Up to 300mA (depends on input/output conditions)  
- **Switching Frequency:** 300kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
The MAX772CSA is a high-efficiency, step-up DC-DC converter designed to generate a regulated output voltage from a low input voltage. It is commonly used in battery-powered applications where a higher voltage is needed from a lower supply.  

### **Features:**  
- **Wide Input Voltage Range (2V to 16.5V)** – Suitable for battery-powered applications.  
- **High Efficiency (Up to 90%)** – Minimizes power loss.  
- **Adjustable or Fixed Output Voltage** – Configurable via external resistors.  
- **Low Quiescent Current (0.3mA typical)** – Extends battery life.  
- **Internal Power MOSFET** – Simplifies design by eliminating the need for an external switch.  
- **300kHz Switching Frequency** – Allows for small external components.  
- **Over-Temperature Protection** – Enhances reliability.  

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