About Non-Isolated DC-DC Converters
Non-isolated DC-DC converters efficiently step down voltage without electrical isolation between input and output. They are ideal for point-of-load (PoL) applications where space and efficiency are critical, such as distributing multiple voltage rails from a central bus in PCBs.
These converters reduce design complexity by integrating controllers, FETs, and inductors into single modules. Their compact footprint and high efficiency make them essential for modern electronics, from industrial systems to portable devices, enabling stable power delivery close to power-hungry components like FPGAs or processors.

Packaging Options
Available in Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® packaging for automated assembly compatibility. Specify your preference at checkout.
