Description

General part information

LT3433 Series

The LT3433 is a 200kHz fixed-frequency current mode switching regulator that provides both step-up and stepdown regulation using a single inductor. The IC operates over a 4V 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.The LT3433 is available in a 16-lead thermally enhanced TSSOP package.Applications12V Automotive SystemsWall Adapter Powered SystemsBattery Power Voltage Buffering
