SCT2620MRER

The SCT2620 is 2.5A buck converter with wide input voltage, ranging from 3.8V to 60V, which integrates an 220mΩ high-side MOSFET. The SCT2620, 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 SCT2620 features programmable switching frequency from 100kHz to 1.2 MHz with an external resistor, which provides the flexibility to optimize either efficiency or external component size. The converter supports external clock synchronization with a frequency band from 100kHz to 1.2MHz. The SCT2620 allows power conversion from high input voltage to low output voltage with a minimum 100ns on-time of highside MOSFET. The device offers programmable soft start to prevent inrush current during the startup of output voltage ramping. The SCT2620 features external loop compensation to provide the flexibility to optimize either loop stability or loop response. The SCT2620 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 10-pin EMSOP package.
