SCT2613 4.5V-60V Vin, 1A, High Efficiency Step-down DCDC Converter
■The SCT2613 is 1A buck converter with wide input voltage, ranging from 4.5V to 60V, which integrates an 500mΩ high-side MOSFET. The SCT2613, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) with 80uA low quiescent current which assists the converter on achieving high efficiency at light load or standby condition.
■The SCT2613 features fixed 480KHz switching frequency, which minimizes the external off chip passive components size and reduces the output ripple.
■The SCT2613 allows power conversion from high input voltage to low output voltage with a minimum 80ns on-time of high-side MOSFET and also supports low dropout operation with a low voltage difference from input to output.
■The device offers fixed 6ms soft start to prevent inrush current during the startup of output voltage ramping, and compensation circuits are implemented internally which allows the device to be used with minimized external components. The SCT2613 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 TSOT23-6L package
