SCT2434CQ 3.6V-40V Vin, 3A, High Efficiency Synchronous Step-down DCDC Converter

The SCT2434CQ is 3A synchronous buck converters
with wide input voltage, ranging from 3.6V to 40V,
which integrates a 60mΩ high-side MOSFET and a
36mΩ low-side MOSFET. The SCT2434CQ, adopting
the peak current mode control, supports the Pulse
Skipping Modulation (PSM) with typical 30uA low
quiescent current which assists the converter on
achieving high efficiency at light load or standby
condition.
The SCT2434CQ features an internal 4ms soft-start
time to avoid large inrush current and output voltage
overshoot during startup. The switching frequency is
fixed 2.1MHz. The SCT2434CQ allows power
conversion from high input voltage to low output
voltage with a minimum 60ns on-time of high-side
MOSFET.
The SCT2434CQ is an Electromagnetic Interference
(EMI) friendly buck converter with implementing
optimized design for EMI reduction. The SCT2434CQ
features Frequency Spread Spectrum FSS with ±6%
jittering span of the 2.1MHz switching frequency and
modulati
