SCT SCT2A26STER

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. Integrates an 500mΩ high - side MOSFET and has 4A peak output current limit to support high peak current application in GPS tracker with 4G Module. Adopting the constant - on time (COT) mode control with integrated loop compensation greatly simplifies the converter off - chip configuration. 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. 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.
