SCT2601 65V输出0.6A 非同步整流DCDC转换器 可替代LMR160006X ，MP2459，MP2456

The SCT2601 is 0.6A buck converter with wide input 
voltage, ranging from 4.5V to 60V, which integrates an
500mΩ high-side MOSFET. The SCT2601, adopting 
the peak current mode control, supports the Pulse 
Skipping Modulation (PSM) with 80uA low quiescent 
current which assists the converter on achieving high 
efficiency at light load or standby condition. 
The SCT2601 features fixed 700KHz switching 
frequency, which minimizes the external off chip 
passive components size and reduces the output
ripple. The SCT2601 allows power conversion from 
high input voltage to low output voltage with a minimum 
80ns on-time of high-side MOSFET and also supports 
low dropout operation with a low voltage difference 
from input to output.
The device offers fixed 6ms soft start to prevent inrush 
current during the startup of output voltage ramping, 
and compensation circuits are implemented internally 
which allows the device to be used with minimized 
external components.
