Tuotteen yleiskatsaus

The LT1339ISW#PBF is a high power synchronous current-mode Switching Regulator Controller drives dual N-channel MOSFETs to create a single IC solution for high power DC/DC converters in applications up to 60V. The LT1339 incorporates programmable average current limiting, allowing accurate limiting of DC load current independent of inductor ripple current. The IC also incorporates user-adjustable slope compensation for minimization of magnetics at duty cycles up to 90%. The LT1339 timing oscillator operating frequency is programmable and can be synchronized up to 150kHz. Minimum off-time operation provides main switch protection. The IC also incorporates a soft start feature that is gated by both shutdown and under voltage lockout conditions. An output phase reversal pin allows flexibility in configuration of converter types, including inverting and negative topologies.
  • Dual N-channel synchronous drive handles up to 10000pF gate capacitance
  • Programmable average load current limiting
  • 5V Reference output with 10mA External loading capability
  • Under-voltage lockout with hysteresis
  • Programmable start inhibit for power supply sequencing and protection
  • Adaptive non-overlapping gate drive prevents shoot-through
