DESCRIPTION:

The SCT2330C is 3A synonous buck converters with up to 28V wide input voltage range, which fully integrates an 80mΩ high-side MOSFET a 42mΩ low-side MOSFET to provide high efficiency step-down DC-DC conversion. The SCT2330C adopts peak
current mode control with the integrated compensation network, which makes SCT2330C easily to be used by minimizing the off-chip component count. The SCT2330C supports the Pulse Skipping Modulation(PSM) with typical 25uA Ultra-Low Quiescent.The SCT2330C is an Electromagnetic Interference(EMI) friendly buck converter with implementing
optimized design for EMI reduction. The converter has proprietary designed gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on turn-off time, which further erases high frequency radiation EMI noise caused by the MOSFETs hard switching.The SCT2330C offers output over-voltage protection,cycle-by-cycle peak current limit, thermal shutdown protection. The device is available in a lowprofile TSOT23-6 package.
