Product Overview

The LT1507CS8#PBF is a monolithic buck-mode Switching Regulator functionally identical to the LT1375 but optimized for lower input voltage applications. It will operate over a 4 to 15V input range, compared with 5.5 to 25V for the LT1375. A 1.5A 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 (3.3V) and adjustable parts are available. A special high speed bipolar process and new design techniques allow this regulator to achieve high efficiency at a high switching frequency. Efficiency is maintained over a wide output current range by keeping quiescent supply current to 4mA and by utilizing a supply boost capacitor to allow the NPN power switch to saturate. A shutdown signal will reduce supply current to 20µA.
  • Uses all surface mount components
  • Saturated switch design (0.3R)
  • Cycle-by-cycle current limiting
  • Easily synchronizable
  • Inductor size as low as 2µH
