The SCT2322 is 2A synonous buck converters with up to 32V wide input voltage range, which fully integrates a 130mΩ high-side MOSFET a 70mΩ low-side MOSFET to provide high efficiency step-down DCDC conversion. The SCT2322 adopts peak current mode control with the integrated compensation network, which makes SCT2322 easily to be used by minimizing the off-chip component count. The SCT2322 supports the Pulse Skipping Modulation (PSM).The SCT2322 features output over-voltage protection, cycle-by-cycle peak current limit, thermal shutdown protection. The device is available in a low-profile TSOT23-6 package.

Application:

•  White Goods, Home Appliance
