Description

The LTC3547BIDDB#TRMPBF is a high-efficiency, dual-channel synchronous step-down DC/DC converter manufactured by Linear Technology. Designed to cater to a wide array of power supply requirements, this compact converter is ideal for portable devices and applications requiring dual power rails.

Key Features:

  • Wide Input Voltage Range: The device supports an input voltage range from 2.5V to 5.5V, making it suitable for single Li-Ion, multi-cell alkaline, or NiMH applications, as well as standard 3.3V and 5V power rails.
  • Dual 800mA Output Channels: Each of the two channels can deliver up to 800mA of continuous output current, providing ample power for demanding applications.
  • High Efficiency: With an up to 95% efficiency and a low quiescent current, the LTC3547BIDDB#TRMPBF ensures minimal power loss and extended battery life for portable devices.
  • Synchronous Operation: The integrated synchronous rectification contributes to high efficiency by reducing power loss during the switching process.
  • Adjustable Frequency: The switching frequency can be adjusted from 300kHz to 2MHz or synchronized to an external clock, offering flexibility in balancing efficiency and external component size.
  • Stable with Ceramic Capacitors: The converter is designed to be stable with ceramic output capacitors, ensuring reliable performance and a smaller overall footprint.
  • Low Dropout Operation: The device maintains a constant output even when the input voltage comes close to the output voltage, providing enhanced performance during battery discharge.
  • Thermal and Overcurrent Protection: Built-in thermal shutdown and current limit protection safeguard the device and the load from damage due to overheating or overcurrent conditions.

Applications:

  • Portable and Battery-Powered Devices
  • Handheld Instruments
  • Medical Devices
  • Wireless Modems
  • GPS Devices

The LTC3547BIDDB#TRMPBF is available in a compact, 10-lead DFN (3mm x 3mm) package, making it an excellent choice for space-constrained applications. Its robust feature set and high performance make it an ideal solution for designers looking to optimize power consumption and efficiency in dual-supply applications.
