Product Overview

The LT3433EFE#PBF is a fixed-frequency current-mode Switching Regulator provides both step-up and step-down regulation using a single inductor. The IC operates over a 4 to 60V input voltage range making it suitable for use in various wide input voltage range applications such as automotive electronics that must withstand both load dump and cold crank conditions. Internal control circuitry monitors system conditions and converts from single switch buck operation to dual switch bridged operation when required, seamlessly changing between step-down and step-up voltage conversion. Optional Burst Mode® operation reduces no-load quiescent current to 100µA and maintains high efficiencies with light loads. Current limit foldback and frequency foldback help prevent inductor current runaway during start-up. Programmable soft-start helps prevent output overshoot at start-up.
  • Automatic step-up and step-down conversion
  • Uses a single inductor
  • Low current shutdown
  • Boosted supply pin to saturate high side switch
  • Frequency foldback protection
  • Current limit foldback protection
  • Current limit unaffected by duty cycle
  • ±1% Output voltage accuracy
