    • Wide Input Voltage Range:.
      • 2.9V to 3.6V if VCC is Connected to VIN (RC filter is needed from VIN to VCC)
      • 2.9V to 16V if VCC is Supplied by External Source
      • 4.5V to 16V if VCC is Supplied by Internal LDO
    • Pseudo 600kHz, 800kHz and 1000kHz Switching Frequency Selection.
    • ±1% Reference Voltage Accuracy Over -40°C to 125°C (internal die temperature)
    • Reliable Protection Mode for input UVLO, output UVP, OTP, Valley and Peak Current Limit (OCP)
    • Compact Package: MQFN5×5-32 (Height=2.5mm max)

     The SQ76115BADE high-efficiency synchronous step-down DC/DC converter operates over a wide input voltage range from 2.9V to 16V which is suitable for 12V input voltage application. And it is capable of delivering 15A output current over a wide ambient temperature range.

    The efficiency is pretty high because it integrates high quality main switch, synchronous switch and inductor inside to minimize the overall loss. The stable internal reference provides ±1% accuracy over -40°C to 125°C (internal die temperature) and it provides accurate regulation for a variety of loads over all operation temperature range.

    The SQ76115BADE adopts the COT architecture to achieve fast transient responses for high step down applications. The device is also equipped with cycle-by-cycle current limit, hiccup over current protection and thermal shutdown protection.

    The SQ76115BADE is available in a compact MQFN5mm×5mm package and the height is no more than 2.5mm. The size is very small with high power density.
