The SCT2A10, adopting the  constant-on time (COT) mode control, supports the  PFM with typical 100uA low quiescent current which  assists the converter on achieving high efficiency at  light load or standby condition.  The SCT2A10 features programmable switching  frequency from 300 kHz to 800kHz, which provides the  flexibility to optimize either efficiency or external  component size. The SCT2A10 offers cycle-by-cycle current limit and  hiccup over current protection, 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.  REVISION HISTORY NOTE: Page numbers for previous revisions may differ from page numbers in the current version.
