Description and Introduction

Switched-Capacitor Voltage Converters The MAX1044CPA+ is a charge pump 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 (Maxim Integrated)  
- **Part Number:** MAX1044CPA+  
- **Type:** Charge Pump DC-DC Converter (Voltage Inverter/Doubler)  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** -Vin (Inverter) or 2x Vin (Doubler)  
- **Output Current:** Up to 10mA  
- **Switching Frequency:** ~10kHz (internal oscillator)  
- **Efficiency:** Up to 99% (depending on configuration)  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The MAX1044CPA+ is a switched-capacitor voltage converter that can invert or double an input voltage. It requires minimal external components (typically just two capacitors) and is commonly used in low-power applications where a negative voltage or higher voltage is needed from a single supply.  

### **Features:**  
- Converts +1.5V to +10V input to -1.5V to -10V (inverter mode) or +3V to +20V (doubler mode).  
- Low power consumption.  
- No inductor required.  
- Internal oscillator (~10kHz).  
- Can be synchronized to an external clock (up to 100kHz).  
- Low output impedance.  
- Space-saving 8-pin DIP package.  

This information is based strictly on the manufacturer's datasheet and product specifications.
