    LT1375/LT1376
    1.5A, 500kHz Step-Down
    Switching Regulators FEATURES
    Constant 500kHz Switching Frequency
    Uses All Surface Mount Components
    Inductor Size Reduced to 5µH
    Easily Synchronizable
    Saturating Switch Design: 0.4Ω
    Effective Supply Current: 2.5mA
    Shutdown Current: 20µA
    Cycle-by-Cycle Current Limiting ■






    ■ 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 ...
