DESCRIPTION：

 

The SCT2130Q is a monolithic, step-down switchmode converter with built-in internal 25mΩ High-Side and 20mΩ Low-Side Power MOSFETs. The device achieves 3A of continuous output current from a 2.8V to 6V input voltage range, with excellent load and line regulation. The output voltage can be regulated to as low as 0.6V. 
The SCT2130Q, adopting the constant-on time (COT) mode control provides fast transient response and eases loop stabilization, greatly simplifies the converter off-chip configuration. 
The SCT2130Q features programmable soft-start time to avoid large inrush current and output voltage overshoot during startup. The SCT2130Q operates in Forced Continuous Conduction Mode (FCCM) to achieve low light load ripple. The switching frequency is fixed 2.1MHz. 
It includes full protection features, such as cycle-bycycle current limit and hiccup over current protection, output under-voltage protection, input under-voltage lockout, and thermal shutdown. 
The SCT2130Q requires a minimal number of external components and is available in a spacesaving QFN-8L 1.5mm*2mm package with Wettable Flank.
