제품 개요

The LT1074CT#PBF is a 5A monolithic bipolar step-down Switching Regulator requires only a few external parts for normal operation. The power switch, all oscillator and control circuitry, all current limit components are included on the chip. The topology is a classic positive buck configuration but several design innovations allow this device to be used as a positive-to-negative converter, a negative boost converter and as a flyback converter. The switch output is specified to swing 40V below ground, allowing the LT1074 to drive a tapped-inductor in the buck mode with output currents up to 10A. It uses a true analogue multiplier in the feedback loop. This makes the device respond nearly instantaneously to input voltage fluctuation and makes loop gain independent of input voltage. As a result, dynamic behaviour of the regulator is significantly improved over previous designs. On-chip pulse by pulse current limiting makes the LT1074 nearly bust-proof for output overloads or shorts.
  • 5A Onboard switch
  • Operates up to 60V input
  • Greatly improved dynamic behaviour
  • Only 8.5mA quiescent current
  • Programmable current limit
  • Micro power shutdown mode
