Description and Introduction

Switch-Mode 1-Cell Li+ Chargers The MAX1926ETC is a voltage regulator from Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
- **MAXIM** (now part of Analog Devices)  

### **Specifications:**  
- **Part Number:** MAX1926ETC  
- **Package:** TDFN-12 (3x3mm)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Dropout Voltage:** 100mV (typical at 300mA)  
- **Quiescent Current:** 30µA (typical)  

### **Descriptions:**  
- The MAX1926ETC is a high-efficiency, step-down DC-DC converter designed for low-power applications.  
- It integrates synchronous rectification for improved efficiency and reduced external component count.  
- Suitable for battery-powered devices, portable electronics, and other space-constrained applications.  

### **Features:**  
- **Low Quiescent Current:** Optimized for battery-operated devices.  
- **Pulse-Width Modulation (PWM) Operation:** Ensures stable performance across load conditions.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent and Thermal Protection:** Enhances reliability.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Small Footprint:** TDFN package saves board space.  

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