SCT2323, SCT2325 3.8V-32V Vin,1.1MHz, 2A Synchronous Step-down DCDC Converter with EMI Reduction

PublishTime：2021-11-11

● The SCT2323 and SCT2325 are 2A, 1.1MHz, 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 step-down DCDC conversion. The SCT2323 and SCT2325 adopt peak current mode control with the integrated compensation network and the output feedback resistors network, which make the device easily to be used by minimizing the off-chip component counts. The SCT2323 and SCT2325 support the Pulse Skipping Modulation (PSM) with typical 20uA Ultra-Low Quiescent and achieved 80% efficiency at 1mA and 85% at 5mA light load conditions.
● The SCT2323 and SCT2325 are Electromagnetic Interference (EMI) friendly buck converters. The SCT2323 and SCT2325 feature Frequency Spread Spectrum (FSS) with ±6% jittering span of the 1.1MHz 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 high frequency ringing without sacrificing MOSFET turn onand turn off time, which further erases high frequency radiation EMI noise caused by the MOSFETs hard switching. When the converter enters PSM mode, the artificial switching node anti-ringing circuit is specially designed to address the radiation EMI noise in the light load condition.
● The SCT2323 and SCT2325 offers output over-voltage protection, cycle-by-cycle peak current limit, and thermal shutdown protection. The device is available in a low-profile TSOT23-6L package.
