SCT2330C 3.8V-28V Vin, 3A同步降压DCDC变换器，EMI降低

DESCRIPTION
The SCT2330C is 3A synchronous buck converters
with up to 28V wide input voltage range, which fully
integrates an 80mΩ high-side MOSFET and a 42mΩ
low-side MOSFET to provide high efficiency step-down
DC-DC conversion. The SCT2330C adopts peak
current mode control with the integrated compensation
network, which makes SCT2330C easily to be used by
minimizing the off-chip component count. The
SCT2330C supports the Pulse Skipping Modulation
(PSM) with typical 25uA Ultra-Low Quiescent.
The SCT2330C 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 SCT2330C offers output over-voltage protection,
cycle-by-cycle peak current limit, and thermal
shutdown protection. The device is available in a lowprofile
TSOT23-6 package.
