    Figure 1 shows the LT1935 generating
    5V. Maximum load with VIN = 3.3V is
    1A; from 2.5V the maximum load is
    600mA. Note that the circuit efficiency D1 SW R1

    SHDN The small size eases system design
    in many applications. Large digital
    systems with dense layouts often
    need point-of-load converters to generate secondary logic supplies. With
    a minimum input voltage of 2.3V, the
    LT1935 can convert power from 2.5V,
    3.3V or 5V logic rails to a higher output
    voltage. Even handheld electronics
    such as cell phones, digital cameras
    and music players require peak power
    levels of several watts to drive LEDs, ...
