Beschreibung

The SCT2452C is 5A buck converter with wide input voltage, ranging from 4.5V to 42V, which integrates an 80mΩ high-side MOSFET. The SCT2452C, 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 SCT2452C features programmable switching frequency from 100kHz to 2.2MHz 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 2.2MHz. The SCT2452C 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 SCT2452C features internal loop compensation to simplify the loop compensation design.The SCT2452C 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.
