Silicontent Technology SCT2401 | Demoboard EV2401-B-02A

Description

The SCT2401 is a high frequency, up to 600mA 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 SCT2401, adopts the peak current mode control with built-in loop compensation to make the chip easy to use. The SCT2401 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 SCT2401 allows power conversion from high input voltage to low output voltage. The SCT2401 supports the Pulse Skipping Modulation (PSM) with typical 90uA low quiescent current. It achieves 85% power efficiency at 10mA light load condition. The SCT2401 offers cycle-by-cycle current limit, thermal shutdown protection and input voltage undervoltage protection. The device is available in a 6-pin small profile TSOT23-6 package.
