DESCRIPTION：

 

The SCT2A15 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 SCT2A00 integrates an 975mΩ high-side MOSFET and has 1.8A peak output current limit when Vin<60V to support high peak current application.
The SCT2A15, adopting the constant-on time (COT) mode control with integrated loop compensation greatly simplifies the converter off-chip configuration. 
The SCT2A15 features Pulse Frequency Modulation (PFM) mode at light load with typical 49uA low quiescent current, which enables the converter to achieve the high-power efficiency during light-load or no-load conditions. 
The SCT2A15 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 SOT23-6L package.
