    The ISL70001ASEH is a radiation hardened and SEE
    hardened high efficiency monolithic synchronous buck
    regulator with integrated MOSFETs. This single chip power
    solution operates over an input voltage range of 3V to 5.5V
    and provides a tightly regulated output voltage that is
    externally adjustable from 0.8V to ~85% of the input voltage.
    Output load current capacity is 6A for TJ < +145В°C.
    The ISL70001ASEH utilizes peak current-mode control for
    excellent output load transient response and features
    integrated compensation and switches at a fixed frequency of
    1MHz to reduce component size and count. In application
    where two POLs are needed, two ISL70001ASEH devices can
    be synchronized 180В° out-of-phase to reduce the overall input
    RMS ripple current. The internal synchronous power switches
    are optimized for high efficiency and good thermal
    The ISL70001ASEH incorporates fault protection for the
    regulator. The protection circuits include input undervoltage,
    output undervoltage, and output overcurrent. ...
