芯洲现货 SCT2632QSTER 3A降压转化器芯片
DESCRIPTION
The SCT2632 is 3A buck converter with wide input voltage, ranging from 4.2V to 60V, which integrates an 220mΩ high-side MOSFET. The SCT2632, 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 SCT2632 features programmable switching frequency from 100 kHz to 1.2 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 100kHz to 1.2MHz. The SCT2632 allows power conversion from high input voltage to low output voltage with a minimum 100ns on-time of highside MOSFET.
The device offers adjustable soft start to prevent inrush current during the startup of output voltage ramping. The SCT2632 features internal loop compensation to simplify the loop compensation design.
The SCT2632 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.
