The
SCT2464Q is 6A synonous buck converters with wide input voltage, ranging
from 3.5V to 36V, which integrates a 30mΩ high-side MOSFET and a 18mΩ low-side
MOSFET. The SCT2464Q, adopting the peak current mode control, supports the
Pulse Skipping Modulation (PSM) with typical 13uA (VBIAS=5V) low quiescent
current which assists the converter on achieving high efficiency at light load
or standby condition.
The
SCT2464Q features adjustable switching frequency from 200 kHz to 1.8 MHz with
an external resistor, which provides the flexibility to optimize either
efficiency or external component size. The converter supports external clock
synonization with a frequency band from 200kHz to 1.8MHz. The SCT2464Q
allows power conversion from high input voltage to low output voltage with a
minimum 60ns ontime of high-side MOSFET.
The
SCT2464Q is an Electromagnetic Interference (EMI) friendly buck converter with
implementing optimized design for EMI reduction. The SCT2464Q features
Frequency Spread Spectrum FSS with ±6% jittering span of the 500kHz switching
frequency and modulation rate 1/512 of switching frequency to reduce the
conducted EMI.
The
SCT2464Q offers cycle-by-cycle current limit and hiccup over current
protection, thermal shutdown protection, output over-voltage protection and
input voltage under-voltage protection. The device is available in 3.5mm*4mm
QFN-14L package.
