Switching regulator
› Low profile <3 mm for SMD
› Turnkey solutions without extra components
Turnkey solution based on EULER and its' typical connection components cover not more than 200 sq. mm of PCB. It means that EULER is one of the most miniature step-down voltage regulator produced at the moment.
  • Сompact size
  • Plugged-in inductor
  • Minimum of external components
  • High efficiency
  • Ultrafast response to load changes
  • Low power consumption at no-load and stanby mode
  • LGA case for proper mounting and effective heat dissipation
  • SCP and OCP
We will help to choose DC/DC solution for your project, provide you with cost and lead time, accept the requirements for custom design. It takes just few minutes in office hours.
