DESCRIPTION:
 
The SCT2325 is 2A synchronous buck converters with up to 32V 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 SCT2325 adopts peak current mode control with the integrated compensation network, which makes SCT2325 easily to be used by minimizing the off-chip component count. The SCT2325 supports the Pulse Skipping Modulation (PSM) with typical 20uA Ultra-Low Quiescent and achieves more than 80% efficient at 1mA and 88% at 5mA light load conditions. 
The SCT2325 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2325 features 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 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 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.
