Description and Introduction

24V Internal Switch, 100% Duty Cycle, Step-Down Converters The MAX1837 is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 30µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-pin SOT23  

### **Descriptions:**  
The MAX1837 is a synchronous step-down DC-DC converter optimized for portable applications. It integrates both high-side and low-side MOSFETs, reducing external component count. The device operates at a fixed 1.2MHz switching frequency, allowing the use of small inductors and capacitors.  

### **Features:**  
- High efficiency (up to 95%)  
- Low quiescent current (30µA)  
- Internal synchronous rectification  
- No external Schottky diode required  
- Adjustable output voltage (0.8V to VIN)  
- Overcurrent and thermal protection  
- Soft-start functionality  
- Small 6-pin SOT23 package  

This information is based solely on the manufacturer's datasheet for the MAX1837.
