Product Overview

The LT3845EFE#PBF is a high voltage synchronous current-mode Controller used for medium to high power 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.
  • Adaptive nonoverlap circuitry prevents switch shoot-through
  • Reverse inductor current inhibit for discontinuous operation improves efficiency with light loads
  • Programmable soft-start
  • 120µA No load quiescent current
  • 10µA Shutdown supply current
  • 1% Regulation accuracy
  • Standard gate N-channel power MOSFETs
  • Current limit unaffected by duty cycle
  • Reverse overcurrent protection
