Introducing the LTC3709EUH: A High-Efficiency, PolyPhase Synchronous Step-Down Switching Regulator

The LTC3709EUH, crafted by the renowned Linear Technology, is a state-of-the-art synchronous step-down switching regulator that boasts exceptional efficiency and performance. This advanced component is designed to meet the rigorous demands of high-performance applications, providing a compact, efficient, and reliable power management solution.

Key Features:

  • PolyPhase® Operation: The LTC3709EUH supports PolyPhase operation, which allows multiple ICs to run out-of-phase, reducing input and output ripple and eliminating the need for large, costly capacitors and inductors. This results in a smaller, lighter power supply that can handle high current requirements with ease.
  • Wide Input Voltage Range: With an input voltage range of 4V to 36V, the LTC3709EUH is versatile enough to accommodate a variety of power sources, making it ideal for applications ranging from automotive to industrial systems.
  • Adjustable Operating Frequency: The operating frequency can be set between 250kHz to 780kHz or synchronized to an external clock, providing design flexibility and optimization of component sizes and efficiency.
  • Robust Output Voltage: The output voltage is adjustable from 0.8V to 5V, enabling precise power delivery to a wide range of digital and analog circuits.
  • Integrated MOSFET Drivers: The LTC3709EUH includes powerful 1.1Ω N-channel MOSFET gate drivers, ensuring robust and efficient switching performance.

Protection and Reliability:

The LTC3709EUH is designed with protection features that ensure reliable operation under adverse conditions. It includes overvoltage protection, overcurrent protection, and thermal shutdown. The device is housed in a compact 5mm x 5mm QFN package, which provides excellent thermal performance and saves board space.


Due to its versatile feature set and robust design, the LTC3709EUH is an excellent choice for various applications, including:

  • Telecommunications Infrastructure
  • Networking Equipment
  • Automotive Power Systems
  • Industrial Supplies
  • High-Density Distributed Power Systems

Whether you're designing a power supply for a sophisticated data center or a rugged automotive application, the LTC3709EUH from Linear Technology provides the efficiency, flexibility, and reliability needed to meet the challenge.
