Description and Introduction

+5V to ±10V Voltage Converters The MAX680ESA+ is a voltage converter IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX680ESA+  
- **Type:** Charge Pump Voltage Converter  
- **Package:** 8-SOIC (150mil)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 1.5V to 6V  
- **Output Voltage Options:** ±5V, ±10V, or adjustable  
- **Output Current:** Up to 10mA  
- **Switching Frequency:** 10kHz (typical)  
- **Quiescent Current:** 1.2mA (typical)  
- **Efficiency:** Up to 99%  

### **Description:**  
The MAX680ESA+ is a monolithic, charge-pump voltage converter that generates ±5V or ±10V outputs from a single +2V to +6V supply. It eliminates the need for inductors and is suitable for low-power applications.  

### **Features:**  
- **No Inductors Required** – Uses external capacitors for voltage conversion.  
- **Low Power Consumption** – Ideal for battery-powered devices.  
- **Wide Input Voltage Range** – Operates from 1.5V to 6V.  
- **High Efficiency** – Up to 99% conversion efficiency.  
- **Small Footprint** – Available in an 8-pin SOIC package.  
- **Simple External Components** – Requires only four capacitors.  

This IC is commonly used in RS-232 interfaces, LCD bias supplies, and other low-power applications requiring dual-rail voltages.

Application Scenarios & Design Considerations

+5V to ±10V Voltage Converters

Alternative Part Number

  • LTC1144CS8#PBF --: Pin-compatible switched-capacitor voltage converter in SO-8 with similar inverting/doubling function and widely available.
  • ICL7660CSA+ --: Classic charge-pump voltage converter offering similar inversion/doubling capability in an 8-pin SO package.
  • TC7660EOA --: Charge-pump voltage converter with comparable function and SO-8 footprint, suitable as a functional substitute.
