    500mA, 2.25MHz
    Synchronous Step-Down
    DC/DC Converter
    FEATURES DESCRIPTION ■ The LTC®3542 is a high efficiency monolithic synchronous
    buck converter using a constant frequency, current mode
    architecture. Supply current during operation is only
    26μA, dropping to <1μA in shutdown. The 2.5V to 5.5V
    input voltage range makes the LTC3542 ideally suited for
    single Li-Ion battery-powered applications. 100% duty
    cycle provides low dropout operation, extending battery
    life in portable systems. The output voltage is adjustable
    from 0.6V to VIN. Internal power switches are optimized
    to provide high efficiency and eliminate the need for an
    external Schottky diode. ■
