Description and Introduction

1-Cell-to-3-Cell, High-Power, Low-Noise, Step-Up DC-DC Converters The MAX848ESE-T is a step-up DC-DC converter manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX848ESE-T  
- **Package:** 16-SOIC (0.154", 3.90mm Width)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Mounting Type:** Surface Mount  
- **Output Type:** Adjustable  
- **Input Voltage Range:** 0.8V to 5.5V  
- **Output Voltage Range:** Adjustable up to 5.5V  
- **Switching Frequency:** 500kHz  
- **Output Current:** Up to 300mA  
- **Efficiency:** Up to 90%  
- **Quiescent Current:** 20µA (typical)  

### **Descriptions:**
The MAX848ESE-T is a high-efficiency, step-up DC-DC converter designed for low-input voltage applications. It is optimized for battery-powered systems, providing a regulated output voltage from a single-cell or dual-cell battery input. The device includes an internal N-channel MOSFET switch and operates at a fixed switching frequency of 500kHz, allowing for compact external components.

### **Features:**
- **Low-Voltage Operation:** Works with input voltages as low as 0.8V.  
- **Adjustable Output Voltage:** Can be set up to 5.5V using external resistors.  
- **High Efficiency:** Up to 90% efficiency, extending battery life.  
- **Low Quiescent Current:** 20µA typical, reducing power consumption in standby mode.  
- **Internal MOSFET Switch:** Eliminates the need for an external switch.  
- **500kHz Switching Frequency:** Enables small external components.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

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