SY21072I - Synchronous Step Down Regulator
The SY21072I is a high efficiency, synchronous stepdown DC/DC converter capable of delivering 2A load current.
The SY21072I operates over a wide input voltage range from 4.2V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
