Switching regulator, LT1376CS8-5#PBF, Linear Technology

The LT1376CS8-5#PBF is a 500 kHz monolithic buck mode switching regulator. A 1.5 A 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 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 20 μA.
