Introducing the LTC3409AIDD: A High-Efficiency, Synchronous Step-Down DC/DC Converter

The LTC3409AIDD is a versatile and compact synchronous step-down DC/DC converter designed by Linear Technology, now part of Analog Devices. This high-efficiency, monolithic integrated circuit is engineered to deliver continuous output currents up to 600mA. Its small size and high efficiency make it an ideal choice for portable and space-constrained applications.

Key Features:

  • High Efficiency: The LTC3409AIDD boasts an efficiency of up to 95%, minimizing power loss and extending battery life in portable devices.
  • Wide Input Voltage Range: It operates from an input voltage range of 2.5V to 5.5V, accommodating a variety of power sources, from single-cell lithium-ion batteries to multi-cell alkaline/NiMH batteries or regulated 5V supplies.
  • Versatile Output Voltage: The output voltage is adjustable from 0.6V to VIN, providing flexibility to power a wide range of low-voltage ICs.
  • High-Frequency Operation: With a switching frequency of up to 3MHz, the LTC3409AIDD allows the use of tiny, low-cost capacitors and inductors, further reducing the solution footprint.
  • No Schottky Diode Required: The internal synchronous rectifier enhances efficiency and eliminates the need for an external Schottky diode, saving board space and component cost.
  • Selectable Burst Mode® Operation: For the highest efficiency at light loads, the LTC3409AIDD features a low quiescent current Burst Mode operation.
  • Stable with Ceramic Capacitors: The device remains stable with high-value, low-ESR ceramic output capacitors, ensuring reliable performance and a small solution footprint.
  • Thermal Protection: It includes thermal shutdown to protect the device under over-temperature conditions.


The LTC3409AIDD is suitable for a wide range of applications, including:

  • Portable Instruments
  • Battery-Powered Equipment
  • Medical Devices
  • Wireless Modems
  • Handheld Computers
  • MP3 Players

With its high level of integration and performance, the LTC3409AIDD is designed to meet the needs of modern, power-sensitive applications. Its small DFN package and minimal external component requirements make it an excellent choice for designers seeking to optimize power management in compact devices.
