DESCRIPTION：
The SCT2322 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 SCT2322 adopts peak current mode control with the integrated compensation network, which makes SCT2322 easily to be used by minimizing the off-chip component count. The SCT2322 supports the Pulse Skipping Modulation (PSM) .
The SCT2322 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. 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 SCT2322 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.
