Description and Introduction

White LED Step-Up Converter in SOT23 The **MAX1848ETA+T** is a product manufactured by **MAXIM** (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** MAXIM (now Analog Devices)  
- **Part Number:** MAX1848ETA+T  
- **Package:** 8-TDFN (3x3mm)  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 150mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:** Low Start-Up Voltage (0.7V), True Shutdown, Internal Soft-Start  

### **Description:**  
The MAX1848ETA+T is a high-efficiency, step-up DC-DC converter designed for low-input-voltage applications. It is optimized for battery-powered devices and can operate from a single-cell battery (0.7V minimum start-up). The device includes an internal N-channel MOSFET switch and provides a regulated output voltage with minimal external components.  

### **Key Features:**  
- **Ultra-Low Input Voltage Operation** (0.7V start-up, 0.5V operating)  
- **Adjustable Output Voltage** (up to 5.5V)  
- **True Shutdown Mode** (disconnects load from input)  
- **Internal Soft-Start** (reduces inrush current)  
- **High Efficiency** (up to 90%)  
- **Compact 8-TDFN Package** (3x3mm)  

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