Download Datasheet Visit Manufacturer Site View Pricing & Stock

The LTC3829 is a high performance 3-phase single output synchronous step-down DC/DC switching controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phase-lockable frequency of up to 770kHz. Power loss and noise due to ESR of the input capacitors are minimized by operating the three controller output stages out of phase.The LTC3829 can be configured for 6-phase operation, has DCR temperature compensation, and output foldback current limiting. This device features a precision 0.6V reference and a power good indicator.Light load efficiency is optimized by using a choice of output Stage Shedding or Burst Mode operation. A differential amplifier provides true remote sensing of the output voltage at the point of load.The LTC3829 is available in both low profile 38-pin 5mm × 7mm QFN and Exposed Pad FE packages.
