Description and Introduction

1-Cell to 3-Cell / High-Power / Low-Noise / Step-Up DC-DC Converters The MAX848ESE is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin narrow SOIC (SO-16)  

### **Descriptions:**  
The MAX848ESE is a high-efficiency, low-voltage step-up DC-DC converter designed for battery-powered applications. It integrates a power switch and synchronous rectifier to minimize external components. The device is optimized for low-input-voltage operation, making it suitable for single-cell or dual-cell battery systems.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Integrated Power Switch and Synchronous Rectifier**  
- **Adjustable Output Voltage** (via external resistors)  
- **Low Quiescent Current:** 20µA (typical)  
- **Pulse-Frequency Modulation (PFM) for Improved Efficiency at Light Loads**  
- **Overcurrent and Thermal Shutdown Protection**  
- **Small External Component Count**  

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

Description and Introduction

1-Cell to 3-Cell / High-Power / Low-Noise / Step-Up DC-DC Converters The MAX848ESE is a 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:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX848ESE  
- **Package:** 16-pin Narrow SOIC (SO)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Switching Frequency:** 500kHz  
- **Maximum Output Current:** 300mA (at 3.3V output)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX848ESE is a high-efficiency, step-up DC-DC converter designed for low-input-voltage applications. It integrates a power MOSFET and is optimized for battery-powered systems. The device provides a regulated output voltage from a single-cell or dual-cell battery input.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Adjustable Output Voltage** (via external resistors)  
- **Internal Power MOSFET** (eliminates the need for an external switch)  
- **Low Quiescent Current:** 35µA (typical)  
- **Pulse-Width Modulation (PWM) Operation**  
- **Thermal Shutdown Protection**  
- **Small Footprint** (16-pin SOIC package)
