SCT2650Q 4.5V-60V Vin, 5A, High Efficiency Step-down DCDC Converter with Programmable Frequency Preliminary Specification
■The SCT2650Q is 5A buck converter with wide input voltage, ranging from 4.5V to 60V, which integrates an 80mΩ high-side MOSFET. The SCT2650Q, 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 SCT2650Q features programmable switching frequency from 100kHz to 1.2MHz 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 1.2MHz. The SCT2650Q allows power conversion from high input voltage to low output voltage with a minimum 130ns on-time of high-side MOSFET.
■The device offers fixed 4ms soft start to prevent inrush current during the startup of output voltage ramping. The SCT2650Q features external loop compensation to provide the flexibility to optimize either loop stability or loop response
■The SCT2650Q 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
