MagI³C-FDSM Fixed Step Down Regulator Module

Characteristics

  • Simplest design (no power supply knowledge required)
  • Leaded through-hole package for easy manufacturing and prototyping
  • Partly integrated CIN / COUT
  • L78x series linear regulator replacement (no heatsink required)
  • Low conducted and radiated EMI (compliant to EN55022 (CISPR-22) class B / EN55032 (CISPR-32) class B)
  • Pin Positions
  • Type B - Pin position at the back as seen from the marking
  • Type F - Pin position at the front as seen from the marking
  • For details see datasheet PIN out section and dimensions!

Applications

  • Point-of-load DC-DC applications of 9V, 12V, 15V, 18V, 24V, 36V and 48V industrial bus
  • Applications for logistics and automation
  • Linear regulator replacement
  • Interface and microcontroller supply
  • Test and measurement technology, medical technology
  • Supply of interfaces
