Product Overview

The LT3840MPFE#PBF is a high voltage synchronous step-down switching Regulator Controller capable of operating from a 2.5 to 60V supply. The LT3840's low quiescent current, when configured for user selectable Burst Mode® operation, helps extend run time in battery-powered systems by increasing efficiency at light loads. The LT3840 uses a constant frequency, current-mode architecture. High current applications are possible with large N-channel gate drivers capable of driving multiple low RDS(ON) MOSFETs. An integrated buck-boost switching regulator generates a 7.5V bias supply voltage for MOSFET gate drive and IC power allowing higher efficiency operation over the entire input voltage range and eliminating the need for an external bias voltage. An accurate current limit set point regulates the maximum output current. A current monitor reports the average output current.
  • Programmable constant-current operation with current monitor output
  • Accurate input overvoltage and undervoltage threshold
  • Programmable soft-start with voltage tracking
  • Power good and output OVP
  • Synchronizable from 50kHz to 1MHz
  • Internal OVLO protects for input transients up to 80V
