Product Overview

The LT3682IDD#PBF is an adjustable frequency monolithic buck Switching Regulator accepts input voltage up to 36V. A high efficiency 0.5R switch is included on the device along with a boost diode and the necessary oscillator, control and logic circuitry. Current-mode topology is used for fast transient response and good loop stability. A SYNC pin allows the user to synchronize the part to an external clock and to choose between low ripple Burst Mode® operation and standard PWM operation. The low ripple Burst Mode® maintains high efficiency at low output currents while keeping output ripple below 15mV in typical applications. 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 90% of the programmed output voltage.
  • Short-circuit protection
  • Soft-start capability
  • Power good flag
  • Overvoltage lockout protects circuits through 60V transients
  • Synchronizable between 300kHz and 2.2MHz
  • 0.8V Feedback reference voltage
