- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX1993ETG is a high-efficiency, synchronous step-down DC-DC controller designed for high-current applications. It operates with external N-channel MOSFETs to provide a regulated output voltage. The device features adjustable switching frequency, soft-start, and overcurrent protection.

### **Features:**
- **Adjustable Output Voltage:** Supports output voltages from 0.8V to 5.5V.  
- **Wide Input Voltage Range:** Operates from 4.5V to 28V.  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Programmable Switching Frequency:** Adjustable from 300kHz to 1MHz.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Uses external MOSFET RDS(ON) sensing.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Power-Good Output:** Monitors output voltage status.  

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