Product Overview

The LT3980EMSE#PBF is a 2.4MHz step-down Switching Regulator with 85µA quiescent current accepts input voltages up to 58V (80V transient). A high efficiency 200mR 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. Catch diode current sense (DA pin) protects the circuit during input voltage transients even when a high switching frequency is used. 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 LT3980 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).
  • Over-voltage lockout protects circuits through 80V transients
  • 100kHz to 2.4MHz Adjustable switching frequency
  • Low shutdown current (IQ <1µA)
  • Catch diode current sense protects circuit through short-circuit and input overvoltage
  • Synchronizable between 250kHz to 2MHz
  • Power good flag
  • Saturating switch design (200mR on-resistance)
  • Thermal protection
  • Soft-start capability
