### **Features:**  
- **Wide Input Voltage Range (4.5V to 28V)**  
- **Adjustable Output Voltage (0.7V to 5.5V)**  
- **Programmable Switching Frequency (50kHz to 600kHz)**  
- **Integrated MOSFET Drivers**  
- **Soft-Start Functionality**  
- **Undervoltage Lockout (UVLO)**  
- **Thermal Shutdown Protection**  
- **PowerPAD™ Package for Enhanced Thermal Performance**  
- **Synchronous Rectification for Improved Efficiency**  

This device is commonly used in telecom, industrial, and computing applications requiring efficient power conversion.

Application Scenarios & Design Considerations

Wide Input (8V-40V) up to 1MHz Frequency Synchronous Buck Controller, source/sink 16-HTSSOP -40 to 85

Alternative Part Number

  • LM2743MTCX/NOPB --: Synchronous buck controller with similar voltage-mode control and wide input range; different series name makes it easy to distinguish from the source.
  • ISL6545IBZ --: Single-phase synchronous buck PWM controller with comparable input voltage and gate drive capability; different manufacturer and prefix provide a clear alternative.
  • LTC3851EGN#PBF --: Wide input range synchronous step-down controller with similar functionality and package options; distinct series naming avoids confusion with the original part.
