SCT2452C 可Pin To Pin替代LMR14050

The SCT2452C is 5A buck converter with wide input
voltage, ranging from 4.5V to 42V, which integrates an
80mΩ high-side MOSFET. The SCT2452C, adopting
the peak current mode control, supports the Pulse
Skipping Modulation (PSM) which assists the converter
on achieving high efficiency at light load or standby
condition.
The SCT2452C features programmable switching
frequency from 100kHz to 2.2MHz with an external
resistor, which provides the flexibility to optimize either
efficiency or external component size. The converter
supports external clock synchronization with a
frequency band from 100kHz to 2.2MHz. The
SCT2452C allows power conversion from high input
voltage to low output voltage with a minimum 130ns ontime of high-side MOSFET.
The device offers adjustable soft start to prevent inrush
current during the startup of output voltage ramping.
The SCT2452C features internal loop compensation to
simplify the loop compensation design.
