DESCRIPTION:
 
The SCT2412 is a high frequency, up to 1A continuous output synchronous buck converter. It has wide input voltage rating from 4.5V to 40V, which integrates a 600mΩ high-side MOSFET and a 300mΩ low-side MOSFET. The S4CT2412, adopts the peak current mode control with built-in loop compensation to make the chip easy to use. The SCT2412 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 SCT2412 allows power conversion from high input voltage to low output voltage. The SCT2412 supports the Pulse Skipping Modulation (PSM) with typical 90uA low quiescent current. It achieves 87% power efficiency at 10mA light load condition. The SCT2412 offers cycle-by-cycle current limit and hiccup protection, thermal shutdown protection, output over-voltage protection and input voltage undervoltage
protection. The device is available in a 6-pin small profile TSOT23-6L package.
