Product Overview

The LT1374CR-5#PBF is a monolithic buck mode Switching Regulator features a 4.5A switch is included on the die along with all the necessary oscillator, control and logic circuitry. High switching frequency allows a considerable reduction in the size of external components. The topology is current mode for fast transient response and good loop stability. Both fixed output voltage and adjustable parts are available. A special high speed bipolar process and new design techniques achieve high efficiency at high switching frequency. Efficiency is maintained over a wide output current range by using the output to bias the circuitry and by utilizing a supply boost capacitor to saturate the power switch. Full cycle-by-cycle short-circuit protection and thermal shutdown are provided. Standard surface mount external parts may be used, including the inductor and capacitors. There is the optional function of shutdown or synchronization.
  • Uses All Surface Mount Components
  • Inductor Size Reduced to 1.8µH
  • Cycle-by-cycle current limiting
  • Easily synchronizable
  • 0.07R Saturating switch design
  • 2.5mA Effective supply current
  • 20µA Shutdown Current
