SY21153A
Description
The SY21153A high-efficiency synchronous stepdown DC/DC converter operates using a peakcurrent-mode control architecture and can deliver 3A load current over a wide input voltage range from 4.5V to 40V. It integrates a main switch and a synchronous switch with low RDS(ON) to minimize conduction loss.
