Product Overview

The LT8309HS5#TRMPBF is a secondary-side Synchronous Rectifier Driver that replaces the output rectifier diode in a fly back topology. By replacing the diode with a N-channel MOSFET, applications are no longer restricted by the heat constraints of the output diode. The IC replicates the behavior of a diode by sensing the drain-to-source voltage to determine when the current becomes negative. The LT8309's low minimum on- and OFF-times help improve noise immunity. The fast propagation delay of 26ns allows applications to operate in discontinuous conduction mode (DCM) and critical conduction mode (CrCM). The gate driver features a 0.8Ω pull-down device for fast turn-OFFs. The 40V VCC rating allows the part to be driven from the output voltage or the rectified drain voltage of the MOSFET. A low quiescent current of 400µA maximizes efficiency at low output currents.
  • Supports up to 150V MOSFETs
  • 26ns Turn-OFF propagation delay
  • Accurate minimum ON and OFF timers for reliable operation
  • 1Ω Gate driver pull-down
  • +5mV to -30mV Adjustable and accurate trip point
  • Green product and no Sb/Br
