Product Overview

The LT3972EDD#PBF is an adjustable frequency monolithic buck Switching Regulator accepts input voltage up to 33V (62V maximum). A high efficiency 95mR 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 LT3972 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 91% of the programmed output voltage.
  • Power good flag
  • Thermal protection
  • Soft-start capability
  • Overvoltage lockout protects circuit through 62V transients
  • Synchronizable between 250kHz to 2MHz
