    Descriptions
    The SC81A10/E is a non-synchronous buck converter
    featuring a wide input voltage range of 6V to 100V, and is
    specifically optimized for applications demanding ultra-low
    standby power consumption. The converter can achieve
    high efficiency and can support up to 1.2A continuous load
    current with integrated Low RON high-side power
    MOSFETs. The SC81A10 integrates a PG pin to indicate
    whether the output is within the target range, while for the
    SC81A10E, the PG pin is replaced by an EXT pin instead.
    The SC81A10E can achieve much lower standby loss and
    higher light-load efficiency via the EXT tied to VOUT.
    The device employs a constant on-time control mode which
    enables a fast transient response. It is compatible with low
    equivalent series resistance output capacitors such as
    polymer and ceramic (MLCC) capacitors with external
    compensation circuits.
    The IC incorporates an internal VCC bias supply, which
    helps to eliminate the need for an external VCC capacitor
    and simplifies PCB layout.
    The device supports protections including input undervoltage
    protection, cycle-by-cycle peak current limitation,
    short circuit protection with hiccup mode, and thermal
    shutdown protection with auto-recovery
    SC81A10/E adopts SOP8 Package
