Product Overview

The LT1959CS8#PBF is a monolithic buck-mode Switching Regulator for use with battery-powered systems. It will operate down to 1.21V output. 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. 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 keeping quiescent supply current to 3.8mA 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 are used, including the inductor and capacitors. A shutdown signal reduces supply current to 15µA.
  • Uses all surface mount components
  • Easily synchronizable
  • Cycle-by-cycle current limiting
  • Current mode control
  • Inductor size reduced to 1.8µH
  • 0.07R Saturating switch design
  • 15µA Shutdown current
