LT1376CS8-5#PBF (LINEAR TECHNOLOGY)

The LT1376CS8-5#PBF is a 500kHz monolithic buck mode Switching Regulators with 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 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. A shutdown signal will reduce supply current to 20µA on both parts. The LT1375 can be externally synchronized from 580 to 900kHz with logic level inputs. Full cycle-by-cycle short-circuit protection and thermal shutdown are provided.
