Description and Introduction

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The **MAX860ISA** is a DC-DC converter manufactured by **Maxim Integrated (now part of Analog Devices)**. Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** DC-DC Switching Regulators  
- **Output Type:** Adjustable  
- **Topology:** Step-Up (Boost)  
- **Output Voltage Range:** Adjustable (specific range depends on configuration)  
- **Output Current:** Up to **100mA** (varies with input/output conditions)  
- **Input Voltage Range:** **1.8V to 5.5V**  
- **Switching Frequency:** **300kHz** (typical)  
- **Efficiency:** Up to **90%** (depending on load and conditions)  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **8-SOIC**  

### **Descriptions:**  
The **MAX860ISA** is a **boost (step-up) DC-DC converter** designed for low-power applications requiring a higher output voltage from a low input voltage source. It is commonly used in battery-powered devices, portable electronics, and other applications where efficient power conversion is critical.  

### **Features:**  
- **Low Input Voltage Operation (1.8V to 5.5V)** – Suitable for single-cell battery applications.  
- **Adjustable Output Voltage** – Allows flexibility for different power requirements.  
- **High Efficiency (Up to 90%)** – Optimizes battery life in portable devices.  
- **Low Quiescent Current (Typ. 50µA)** – Minimizes power loss in standby mode.  
- **Internal Power Switch** – Simplifies design by eliminating the need for an external MOSFET.  
- **300kHz Switching Frequency** – Reduces the size of external components.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Small 8-SOIC Package** – Space-efficient for compact designs.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application circuits and performance graphs, refer to the official **MAX860ISA datasheet**.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LT1054CS8 --: Pin-compatible switched-capacitor voltage converter/inverter with similar function and SO-8 package, widely used as a MAX860 substitute.
  • ICL7660SCPA --: Classic charge-pump voltage inverter offering comparable inverting/voltage-conversion function, though package and current rating differ slightly.
  • TC7660EOA --: Low-cost charge-pump voltage converter in SOIC package providing similar inversion/doubling function for less demanding loads.
  • TC7660COA --: Charge-pump voltage converter in SO-8 with similar functionality; good cost-effective substitute when full MAX860 current is not required.
