Description and Introduction

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The MAX860ESA is a high-efficiency, step-up DC-DC converter 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 (now Analog Devices)  
- **Part Number:** MAX860ESA  
- **Package:** 8-pin SOIC  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX860ESA is a low-power, step-up DC-DC converter designed for battery-powered applications. It features a high-efficiency switching regulator that boosts low input voltages (as low as 0.7V) to a higher, adjustable output voltage. The device is optimized for space-constrained designs and operates with minimal external components.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **High Efficiency:** Up to 90% conversion efficiency.  
- **Low Quiescent Current:** 30µA (typical).  
- **Internal MOSFET Switch:** Simplifies design and reduces external components.  
- **Automatic Pulse-Frequency Modulation (PFM):** Improves efficiency at light loads.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Small Footprint:** 8-pin SOIC package for compact designs.  

This information is based on the manufacturer's datasheet and technical documentation.

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.
