SCT2A27 5.5V-100V Vin, 4A Peak Current Limit, High Efficiency Asynchronous Step-down DCDC Converter with a 200mA LDO Integrated
●The SCT2A27 is an asynchronous buck converter with wide input voltage ranging from 5.5V to 100V which accommodates a variety of step-down applications, making it ideal for automotive, industry, and lighting applications. The SCT2A27 integrates an 500mΩ high-side MOSFET and has 4A peak output current limit to support high peak current application in GPS trackerwith 4G Module. The SCT2A27 also integrate a 200mA LDO which can provide 5V or 3.3V power rail for the system.
●The SCT2A27, adopting the constant-on time (COT) mode control with integrated loop compensation greatly simplifies the converter off-chip configuration.
●The SCT2A27 features Pulse Frequency Modulation (PFM) mode at light load with low quiescent current design, which enables the converter to achieve thehigh-power efficiency during light-load or no-load conditions.
●The SCT2A27 offers 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 thermally enhanced SOP-8 package.
