DESCRIPTION
The SCT2650 is 5A buck converter with wide input
voltage, ranging from 4.5V to 60V, which integrates an
80mΩ high-side MOSFET. The SCT2650, 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 SCT2650 features programmable switching
frequency from 100kHz to 1.2MHz 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 1.2MHz. The SCT2650
allows power conversion from high input voltage to low
output voltage with a minimum 130ns on-time of highside MOSFET.
The device offers fixed 4ms soft start to prevent inrush
current during the startup of output voltage ramping.
The SCT2650 features external loop compensation to
provide the flexibility to optimize either loop stability or
loop response.
The SCT2650 provides cycle-by-cycle current limit,
thermal shutdown protection, output over-voltage
protection and input voltage under-voltage protection.
The device is available in an 8-pin ESOP-8 package.
