The SCT2260A 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
6A
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 SCT2260A 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 SCT2260A features Full protection includes over
current protection, under-voltage protection, thermal shutdown.
