Description and Introduction

Switch-Mode 1-Cell Li+ Chargers The MAX1926ETC is a step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** MAX (Maxim Integrated)  
- **Part Number:** MAX1926ETC  
- **Package:** TQFN-12  
- **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 (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1926ETC is a high-efficiency, step-down DC-DC converter designed for low-power applications. It integrates synchronous rectification, reducing the need for external Schottky diodes. The device operates at a fixed 1MHz switching frequency, allowing for small external components. It features a low-dropout (LDO) mode for improved efficiency at light loads.  

### **Features:**  
- **Synchronous Rectification** for high efficiency  
- **1MHz Fixed Switching Frequency** for compact designs  
- **Low-Dropout (LDO) Mode** enhances light-load efficiency  
- **Adjustable Output Voltage (0.8V to VIN)**  
- **Internal Soft-Start** reduces inrush current  
- **Overcurrent and Thermal Shutdown Protection**  
- **Small 12-Pin TQFN Package (3mm x 3mm)**

- **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.
