DESCRIPTION：

 

The SCT2320E is 2A synchronous buck converters with up to 28V wide input voltage range, which fully integrates an 130mΩ high-side MOSFET and a 70mΩ low-side MOSFET to provide high efficiency step-down DC-DC conversion. The SCT2320E adopts peak current mode control with the integrated compensation network, which makes SCT2320E easily to be used by minimizing the off-chip component count. The SCT2320E supports the Pulse Skipping Modulation (PSM) with typical 40uA Low Quiescent. The SCT2320E is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2320E features Frequency Spread Spectrum FSS with ±6% jittering span of the 410kHz switching frequency and modulation rate 1/512 of switching frequency to reduce the conducted EMI. The converter has proprietary
designed gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off time, which further erases high frequency radiation EMI noise caused by the MOSFETs hard switching.The SCT2320E offers output over-voltage protection,cycle-by-cycle peak current limit, hiccup protection, and thermal shutdown protection. The device is available in a low-profile SOT23-6L package.
