Product Overview

The LT3972EMSE#PBF is a 2.4MHz step-down Switching Regulator with 75µA quiescent current accepts input voltages 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 currents 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.
  • Over-voltage lockout protects circuits through 62V transients
  • 200kHz to 2.4MHz Adjustable switching frequency
  • Low shutdown current (IQ <1µA)
  • Integrated boost diode
  • Synchronizable between 250kHz to 2MHz
  • Power good flag
  • Saturating switch design (95mR on-resistance)
  • Thermal protection
  • Soft-start capability
