General Description

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.

The SY21072I adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads.
