Product Overview

The LT3480HMSE#PBF is an adjustable frequency monolithic buck Switching Regulator accepts input voltage up to 36V (60V maximum). A high efficiency 0.25R 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 currents while keeping output ripple below 15mV in a typical application. In addition, the LT3480 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 86% of the programmed output voltage.
  • Integrated boost diode

  • Soft-start capability
  • Overvoltage lockout protects circuits through 60V transient
  • Synchronizable between 250kHz to 2MHz
  • <1µA Low shutdown current
  • 0.790V Feedback reference voltage
