The SCT9330C is 3A synchronous buck converters with up to 28V wide input voltage range, which fully integrates 115mΩ high-side MOSFET and 70mΩ lowside MOSFET to provide high efficiency step-down DCDC conversion. The SCT9330C adopts peak current mode control with the integrated compensation network, which makes SCT9330C easily to be used by minimizing the off-chip component count. The SCT9330C supports the Pulse Skipping Modulation (PSM) with typical 25uA Ultra-Low Quiescent. The SCT9330C is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT9330C features Frequency Spread Spectrum FSS with ±6% jittering span of the 400kHz 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 SCT9330C offers output over-voltage protection, cycle-by-cycle peak current limit, and thermal shutdown protection. The device is available in ESOP-8L package.
