Description and Introduction

500kHz Multi-Output, Low-Noise Power-Supply Controllers for Notebook Computers The MAX1901ETJ+T is a power management IC (PMIC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now Analog Devices)  

### **Part Number:**  
- **MAX1901ETJ+T**  

### **Description:**  
The MAX1901ETJ+T is a highly integrated power-management IC designed for portable applications. It combines a step-down DC-DC converter with a linear regulator, providing efficient power conversion and management for systems requiring multiple voltage rails.  

### **Key Features:**  
1. **Step-Down DC-DC Converter:**  
   - Input Voltage Range: **2.7V to 5.5V**  
   - Adjustable Output Voltage Range: **1.25V to 3.3V**  
   - Output Current: **Up to 1.2A**  
   - High Efficiency (up to **95%**)  

2. **Linear Regulator (LDO):**  
   - Input Voltage Range: **2.7V to 5.5V**  
   - Fixed Output Voltage: **3.3V** (or adjustable)  
   - Output Current: **Up to 300mA**  

3. **Additional Features:**  
   - **Low Quiescent Current** (typically **60µA**)  
   - **Power-OK (POK) Output** for monitoring  
   - **Soft-Start Function** to limit inrush current  
   - **Thermal Shutdown Protection**  
   - **Overcurrent Protection**  

4. **Package:**  
   - **32-Pin TQFN (5mm x 5mm)**  

5. **Applications:**  
   - Portable devices (PDAs, smartphones, tablets)  
   - Battery-powered systems  
   - Low-power embedded systems  

This IC is designed for space-constrained applications requiring efficient power conversion and management.  

(Note: Specifications are based on the manufacturer's datasheet and may vary slightly depending on operating conditions.)
