Product Overview

The LT3845AEFE#PBF is a current-mode Synchronous Controller used for medium to high power and high efficiency supplies. It offers a wide 4 to 60V input range (7.5V minimum start-up voltage). An onboard regulator simplifies the biasing requirements by providing IC power directly from VIN. Burst Mode® operation maintains high efficiency at light loads by reducing IC quiescent current to 120µA. Light load efficiency is also improved with the reverse inductor current inhibit function which supports discontinuous operation. Additional features include adjustable fixed operating frequency that can be synchronized to an external clock for noise sensitive applications, gate drivers capable of driving large N-channel MOSFETs, a precision undervoltage lockout, 10µA shutdown current, short-circuit protection and a programmable soft-start.
  • High voltage
  • Stable operation in current limit
  • Adaptive non-overlap circuitry prevents switch shoot-through
  • Reverse inductor current inhibit for discontinuous operation improves efficiency with light loads
  • Programmable soft-start
  • 1% Regulation accuracy
  • Standard gate N-channel power MOSFETs
  • Reverse overcurrent protection
