DESCRIPTION
The SCT2401F features fixed 1.2MHz switching frequency, which minimizes the external off chip passive components size and reduces the output ripple to be lower than 0.1% of output when the output is 12V. With a minimum 80ns on-time of high-side MOSFET, the SCT2401F allows power conversion from high input voltage to low output voltage. The SCT2401F supports the Force Pulse Width Modulation (FPWM) mode to achieve small output ripple at light load mode. The SCT2401F offers cycle-by-cycle current limit, thermal shutdown protection and input voltage undervoltage protection.
