Description and Introduction

+12V, 120mA Flash Memory Programming Supply The MAX734CSA is a switched-capacitor voltage inverter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX734CSA  
- **Type:** Switched-Capacitor Voltage Inverter  
- **Input Voltage Range:** +1.5V to +5.5V  
- **Output Voltage:** -1.5V to -5.5V (adjustable)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 250kHz  
- **Efficiency:** Up to 99%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Pin Count:** 8  

### **Descriptions:**  
The MAX734CSA is a charge-pump voltage inverter that efficiently converts a positive input voltage to a negative output voltage. It eliminates the need for inductors, making it suitable for compact designs. The device operates with minimal external components, typically requiring only two flying capacitors and two bypass capacitors.  

### **Features:**  
- **Inductorless Design:** Uses switched-capacitor technology for voltage inversion.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Adjustable Output Voltage:** Can be set via external resistors.  
- **High Efficiency:** Up to 99% conversion efficiency.  
- **Low Output Impedance:** Ensures stable voltage regulation.  
- **Small Footprint:** Requires minimal external components.  
- **Shutdown Mode:** Includes a shutdown pin to reduce power consumption when inactive.
