DESCRIPTION：
The SCT2653 is 5A buck converter with wide input voltage, ranging from 4.5V to 60V, which integrates an 80mΩ high-side MOSFET. The SCT2653, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) which assists the converter on achieving high efficiency at light load or standby condition.
The SCT2653 features fixed 570KHz switching frequency. The SCT2653 allows power conversion from high input voltage to low output voltage with a minimum 130ns on-time of high-side MOSFET.
The device offers adjustable soft start to prevent inrush current during the startup of output voltage ramping. The SCT2653 features external loop compensation to provide the flexibility to optimize either loop stability or loop response.
The SCT2653 provides cycle-by-cycle current limit, thermal shutdown protection, output over-voltage protection and input voltage under-voltage protection. The device is available in an 8-pin ESOP-8 package.
