The SCT2A22, adopting the constant-on time (COT) mode control, supports the Forced PWM mode to achieve smaller output ripple and support Isolation buck topology. The SCT2A22 Features programmable switching frequency from 100 k Hz to 600KHz with an external resistor, which provides the flexibility to optimize either efficiency or external ponent size. The SCT2A22 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. APPLICATIONS - 48V Industry Power Bus System - E-bike,...
