    December 12, 2014 55V Synchronous Buck Controller with Integrated 3A Driver Features The ISL78268 is a grade 1, automotive, synchronous buck
    controller with integrated high/low side MOSFET drivers. It
    supports a wide operating input voltage range of 5V to 55V
    and up to 60V at VIN when not switching. The integrated driver
    offers adaptive dead-time control and is capable of supplying
    up to 2A sourcing and 3A sinking current, allowing the
    ISL78268 to support power stages designed for a wide range
    of loads, from under 1A to over 25A. Wide input range 5V to 55V (switching); withstand 60V
    (non-switching) Integrated 2A sourcing, 3A sinking MOSFET drivers Constant current regulation/limiting -dedicated average
    current control loop Adjustable switching frequency or external synchronization
    from 50kHz up to 1.1MHz ISL78268’s fully synchronous architecture enables power
    conversion with very high efficiency and improved thermal
    performance over standard buck converters. The ISL78268 also
    offers diode emulation mode for improved light load efficiency. Low shutdown current, IQ <1ВµA Peak current mode control with adjustable slope
    compensation Selectable diode emulation mode for high efficiency at light
    load Input and output OVP, cycle-by-cycle current limiting,
    average current OCP, OTP Selectable hiccup or latch-off fault responses Pb-free 24 Ld 4x4 QFN package (RoHS compliant) While ISL78268 is a peak current mode PWM controller, it
    also includes a dedicated average output current modulation
    loop, which achieves constant output current limiting for
    applications such as battery charging, super-cap charging, and ...
