The SCT2401F is a high frequency, up to 600mA continuous output synonous buck converter. It has wide input voltage rating from 4.5V to 40V, which integrates a 600mΩ high-side MOSFET a 300mΩ low-side MOSFET. The SCT2401F, adopts the peak current mode control with built-in loop compensation to make the chip easy to use. The SCT2401F features fixed 1.2MHz switching frequency, which minimizes the external off chip passive components size 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 input voltage undervoltage protection. The device is available in a 6-pin small profile TSOT23-6 package.
