Product Overview

The LT3980IMSE#PBF is an adjustable frequency monolithic buck Switching Regulator accepts input voltage 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 current 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).
  • Power good flag
  • Thermal protection
  • Soft-start capability
  • Catch diode current sense protects circuit through short-circuit and input overvoltage
  • Synchronizable between 250kHz to 2MHz
  • Overvoltage lockout protects circuits through 80V transients
  • 85µA at 12VIN to 3.3VOUT Low ripple (<15mVP-P) Burst Mode® operation
