Description and Introduction

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The MAX860ESA is a voltage regulator IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX860ESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage:** Adjustable (via external resistors) or fixed (3.3V, 5V, etc., depending on variant)  
- **Output Current:** Up to 100mA  
- **Dropout Voltage:** Typically 100mV at 100mA load  
- **Quiescent Current:** Typically 30µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Switching Frequency:** 500kHz (typical)  

### **Descriptions:**  
- The MAX860ESA is a low-dropout (LDO) linear regulator or step-up DC-DC converter (depending on configuration).  
- It is designed for battery-powered applications requiring efficient power conversion with minimal external components.  
- The device can operate in either step-up (boost) or step-down (buck) mode, depending on the configuration.  

### **Features:**  
- **Low Quiescent Current:** Ideal for battery-operated devices.  
- **Adjustable or Fixed Output Voltage:** Configurable via external resistors or factory-set.  
- **High Efficiency:** Optimized for low-power applications.  
- **Low Dropout Voltage:** Ensures stable operation even with small input-output differentials.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Enhances reliability in fault conditions.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes or circuit configurations, refer to Maxim Integrated's official resources.

Application Scenarios & Design Considerations

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters

Alternative Part Number

  • LT1054CS8 --: Pin-compatible switched-capacitor voltage converter in SO-8 with similar inverting/doubling function and current capability; widely used as a MAX860 substitute.
  • ICL7660SCPA --: Classic charge-pump voltage inverter offering similar inverting/doubling operation; lower current rating but a common drop-in for low-load designs.
  • TC7660HEOA --: High-frequency charge-pump inverter in SO-8 with improved output current over the standard 7660, suitable as a functional replacement for MAX860 in many circuits.
  • ICL7660CSA --: Classic charge-pump voltage converter offering inverting and doubling modes, functionally similar to MAX860 and available in SOIC-8.
  • TC7660EOA --: Charge-pump voltage converter in SOIC-8 with comparable inverting/doubling capability, suitable as a lower-cost functional substitute.
