Description and Introduction

Switched-Capacitor Voltage Converters The MAX1044CSA+T is a charge pump DC-to-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
MAXIM (Maxim Integrated)  

### **Specifications:**  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage Options:**  
  - Inverts input voltage (-VIN)  
  - Doubles input voltage (2×VIN)  
- **Output Current:** Up to 20mA  
- **Switching Frequency:** ~10kHz (typical)  
- **Efficiency:** Up to 99% (theoretical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC (CSA+)  

### **Descriptions:**  
- The MAX1044CSA+T is a switched-capacitor voltage converter that generates a negative or doubled output voltage from a single positive supply.  
- It does not require inductors, making it suitable for space-constrained applications.  
- It is pin-compatible with the industry-standard ICL7660 and LTC1044.  

### **Features:**  
- **Low Power Consumption:** Typically 80µA operating current.  
- **No External Diodes Required:** Internal charge pump circuitry eliminates the need for external diodes.  
- **Low Output Impedance:** ~70Ω (typical).  
- **Wide Input Voltage Range:** Supports operation from 1.5V to 10V.  
- **Bootstrap Mode:** Can be configured to generate higher voltages by cascading multiple devices.  

This device is commonly used in applications requiring voltage inversion or doubling, such as in portable electronics, data acquisition systems, and analog signal processing.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)
