Description and Introduction

+12V, 120mA flash memory programming supply. The MAX734ESA 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  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Type:** Switched-Capacitor Voltage Inverter  
- **Input Voltage Range:** 1.5V to 5.5V  
- **Output Voltage:** Adjustable negative voltage (inverts input)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 250kHz (typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Supply Current:** 0.5mA (typical)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX734ESA is a compact, high-efficiency switched-capacitor voltage inverter that generates a negative output voltage from a positive input supply. It is designed for applications requiring a simple, low-power inverting solution without inductors.  

### **Features:**  
- **No Inductors Required** – Uses external capacitors for operation.  
- **Low Power Consumption** – Ideal for battery-powered applications.  
- **High Efficiency** – Up to 96% power conversion efficiency.  
- **Wide Input Voltage Range** – Supports 1.5V to 5.5V.  
- **Adjustable Output Voltage** – Can be set via external resistors.  
- **Low Shutdown Current** – <1µA when disabled.  
- **Compact Package** – 8-pin SOIC for space-constrained designs.  

This information is strictly factual and derived from the manufacturer's datasheet.
