Introduction

AI Translation

The SCT9320 is 2A synchronous buck converters with up to 32V wide input voltage range, which fully integrates a 130mΩ high-side MOSFET and a 70mΩ low-side MOSFET to provide high efficiency stepdown DCDC conversion. The SCT9320 adopts peak current mode control with the integrated compensation network, which makes SCT9320 easily to be used by minimizing the off-chip component count. The SCT9320 supports the Pulse Skipping Modulation (PSM) with typical 20uA Ultra-Low Quiescent and achieves more than 85% efficient at 1mA and 89% at 5mA light load conditions. The SCT9320 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT9320 features Frequency Spread Spectrum FSS with ±6% jittering span of the 500kHz 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 SCT9320 offers output over-voltage protection, cycle-by-cycle peak current limit, and thermal shutdown protection. The device is available in a lowprofile SOP-8L package.
