    ? 2.7V to 16V with external 3.3V VCC bias;
    ? 4V to 16V with internal bias or external 3.3V VCC bias.
    Remote detection with differential output voltage;
    Adjustable precise current limit;
    12A output current;
    Low Rds(on) integrated power MOS;
    Proprietary switching loss reduction technology;
    Adaptive COT, achieving ultra-fast transient response;
    Stably use zero ESR output capacitors;
    0.5% reference voltage within the junction temperature range of 0℃ to 70℃;
    1% reference voltage within the junction temperature range of -40℃ to 125℃;
    The Skip or Forced CCM working mode can be selected.
    It has an excellent load regulation rate;
    During a power failure, the PGOOD active clamp is at a low level.
    Programmable soft start time, starting from 1 millisecond;
    Optional switching frequencies of 600kHz, 800kHz and 1000kHz;
    It has Non-Latch OCP, UVP, UVLO, Thermal Shutdown, and Latch-Off for OVP;
    The output can be adjusted within the range of 0.6V to 90%Vin, with a maximum of 5.5V.
    It adopts a QFN 3mm×4mm package.

Scheme specifications

    A 16V, 12A synchronous step-down converter with adjustable voltage, frequency and current limit.
