Description and Introduction

3.3V/5V/Adjustable-Output, Step-Up DC-DC Converters The MAX757CPA is a step-up DC-DC converter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage Range:** Adjustable from 2.7V to 16.5V  
- **Output Current:** Up to 1A (depending on input/output conditions)  
- **Switching Frequency:** 170kHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The MAX757CPA is a high-efficiency, step-up (boost) DC-DC switching regulator. It is designed to provide a regulated output voltage higher than the input supply. The device includes an internal N-channel power MOSFET switch and requires minimal external components, making it suitable for battery-powered applications.  

### **Features:**  
- **Adjustable Output Voltage** (via external resistor divider)  
- **Low Quiescent Current:** 110µA (typical)  
- **Internal Power MOSFET Switch** (eliminates need for external transistor)  
- **Soft-Start Function** (reduces inrush current)  
- **Undervoltage Lockout (UVLO)** (ensures proper operation at low input voltages)  
- **Current-Limiting Protection** (prevents damage during overloads)  

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