The SY2A22402 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 0.6A load current. The device operates over a wide input voltage range from 4.25V to 40V and integrates main switch and synchronous switch with low RDS(ON) to minimize the conduction loss.
The SY2A22402 adopts peak current control scheme and offers an adjustable version. The SY2A22402 operates under 500kHz fixed switching frequency.
The device also features ultra low quiescent operating to achieve high efficiency under light load. And the internal soft-start limits inrush current during power on.
