The SCT2280 is a high efficiency synonous step-down DC-DC converter with 4.5V-18V input voltage range adjustable output voltage down to 0.6V. It offers a small saving 2mmx3mm QFN package that supplies continuous 8A output current. The device adopts a Constant On-Time (COT) control to provide fast transient response easy loop stabilization. The switching clock frequency can be ed from 400KHz, 800KHz 1.2MHz for optimization of the filter size output voltage ripple. The device offers programmable soft start to prevent inrush current during the startup of output voltage ramping. Power Good with open drain output signals that the output voltage is within regulation. The SCT2280 has the MODE pin to Pulse Frequency Modulation (PFM) operation mode to achieve the light load power save, or Ultrasonic Mode (USM) to keep the switching frequency above audible frequency areas during light-load or no-load conditions.  The SCT2280 features Full protection includes over current protection, under-voltage protection, thermal shutdown.
