SCT2462Q 可替代LM61460-Q1，LM61460

The SCT2462Q is 6A synchronous buck converters 
with wide input voltage, ranging from 3.5V to 40V, 
which integrates a 30mΩ high-side MOSFET and a 
18mΩ low-side MOSFET. The SCT2462Q, 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 SCT2462Q features adjustable switching 
frequency from 200 kHz to 2.2 MHz 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 200kHz to 2.2MHz. The 
SCT2462Q allows power conversion from high input
voltage to low output voltage with a minimum 60ns ontime of high-side MOSFET.
The SCT2462Q is an Electromagnetic Interference 
(EMI) friendly buck converter with implementing 
optimized design for EMI reduction.
