The SCT2A27 is an asynonous 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, lighting applications. The SCT2A27 integrates an 500mΩ highside MOSFET has 4A peak output current limit to support high peak current application in GPS tracker with 4G Module. 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 typical 140uA low quiescent current, which enables the converter to achieve the high-power efficiency during light-load or no-load conditions.The SCT2A27 offers cycle-by-cycle current limit hiccup over current protection, thermal shutdown protection, output over-voltage protection input voltage under-voltage protection. The device is available in an 8-pin thermally enhanced SOP-8package.
