    GENERAL DESCRIPTION


    The SLB628 is a constant frequency, 6-pin SOT23
    current mode step-up converter intended for small,
    low power applications. The SLB628 switches at
    1.2MHz and allows the use of tiny, low cost
    capacitors and inductors 2mm or less in height.
    Internal soft-start results in small inrush current and
    extends battery life.
    The SLB628 features automatic shifting to pulse
    frequency modulation mode at light loads. The
    SLB628 includes under-voltage lockout, current
    limiting, and thermal overload protection to prevent
    damage in the event of an output overload. The
    SLB628 is available in a small 6-pin SOT-23
    package.
