Product Overview

The LT3481IMSE#PBF is an adjustable frequency monolithic buck Switching Regulator accepts input voltage up to 34V (36V maximum). A high efficiency 0.18R switch is included on the die along with a boost Schottky diode and the necessary oscillator, control and logic circuitry. Current-mode topology is used for fast transient response and good loop stability. Low ripple Burst Mode® operation maintains high efficiency at low output current while keeping output ripple below 15mV in a typical application. In addition, the LT3481 can further enhance low output current efficiency by drawing bias current from the output when VOUT is above 3V. Shutdown reduces input supply current to less than 1µA while a resistor and capacitor on the RUN/SS pin provide a controlled output voltage ramp (soft-start). A power good flag signals when VOUT reaches 90% of the programmed output voltage.
  • Integrated boost diode
  • Power good flag
  • Soft-start capability
  • Synchronizable between 275 to 475kHz
  • 1.265V Feedback reference voltage
